This book was released on 2015 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction induced lateral spreading during earthquakes poses a significant hazard to infrastructure and has severe consequences. It is critical for geotechnical earthquake engineers to be able to accurately predict lateral spread movements. Empirical and semi-empirical models and various liquefaction index parameters are available to help predict the potential for damage and movements associated with liquefaction and lateral spreading. In this thesis, the available models and liquefaction index parameters were investigated using the observed lateral spread displacements from the Christchurch earthquake in New Zealand. The analysis includes investigation of the Youd et al. (2002), Bardet et al. (2002), Rauch and Martin (2000) and Zhang et al. (2004) displacement models; and the liquefaction potential index (LPI), settlement indicator (Sv1d) and liquefaction severity number (LSN) parameters. The results of this study show that both the Youd et al. (2002) and Bardet et al. (2002) models predict lateral spread displacements much smaller than observed in Christchurch, most likely due to the relatively small magnitude of the Christchurch earthquake (M[subscript w] = 6.2) relative to the earthquake magnitudes included in datasets used to develop the Youd et al. (2002) and Bardet et al. (2002) models (i.e., Mw >= 7.5). The Rauch and Martin (2000) and Zhang et al. (2004) models predicted lateral spread displacements more similar to those observed. The Rauch and Martin (2000) model predicts the average lateral spread displacement over an entire slide area, as opposed to predicting lateral spread displacement at a point, which may have contributed to the more favorable comparison.

Secara and published by . This book was released on 2016 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction is a significant earthquake hazard that can generate large horizontal displacements associated with lateral spreading and these displacements cause considerable damage. To improve our understanding of liquefaction-induced lateral spreading and the models that can be used to predict the associated displacements, the collection of high quality field data on lateral spreading displacements is essential. Remote sensing techniques, in particular optical image correlation using satellite imagery, can be used for this purpose. This thesis investigates optical image correlation of satellite images as a remote sensing technique for this purpose using images from the 2010-2011 Canterbury earthquake sequence in New Zealand. Optical image correlation uses two optical images – one before and one after the investigated event – to measure displacements that have occurred between the time of the two image acquisitions. The correlation analysis calculates the horizontal displacement at a specified spacing, and the displacements are post-processed and filtered to attain the final displacement field. The displacement results from optical image correlation agreed favorably with qualitative field observations of the severity of liquefaction and lateral spreading, as well as the general crack patterns along the Avon River. A more quantitative comparison was performed using field measured displacements along four linear transects that extended perpendicular from the Avon River. The displacements from optical image correlation also agreed favorably with the field measured displacement profiles, although the optical image correlation displacements somewhat larger than the field measurements. This discrepancy occurs because field measurements are based on discrete measurements of crack width, while the optical image correlation are based on average displacements over larger areas and include displacements associated with ductile movements that may not result in cracking. The results from this research show that optical image correlation of satellite imagery pairs can provide accurate and detailed measurements of horizontal displacements due to liquefaction and lateral spreading. This approach can be used to create more complete and detailed databases of liquefaction-induced movements, which can be used to improve current predictive models for lateral spread displacements. Future post-earthquake investigations and research should make use of optical image correlation to document the displacements associated with liquefaction.

This book was released on 2019-01-30 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquake-induced soil liquefaction (liquefaction) is a leading cause of earthquake damage worldwide. Liquefaction is often described in the literature as the phenomena of seismic generation of excess porewater pressures and consequent softening of granular soils. Many regions in the United States have been witness to liquefaction and its consequences, not just those in the west that people associate with earthquake hazards. Past damage and destruction caused by liquefaction underline the importance of accurate assessments of where liquefaction is likely and of what the consequences of liquefaction may be. Such assessments are needed to protect life and safety and to mitigate economic, environmental, and societal impacts of liquefaction in a cost-effective manner. Assessment methods exist, but methods to assess the potential for liquefaction triggering are more mature than are those to predict liquefaction consequences, and the earthquake engineering community wrestles with the differences among the various assessment methods for both liquefaction triggering and consequences. State of the Art and Practice in the Assessment of Earthquake-Induced Soil Liquefaction and Its Consequences evaluates these various methods, focusing on those developed within the past 20 years, and recommends strategies to minimize uncertainties in the short term and to develop improved methods to assess liquefaction and its consequences in the long term. This report represents a first attempt within the geotechnical earthquake engineering community to consider, in such a manner, the various methods to assess liquefaction consequences.

Download or read book Earthquake induced Ground Deformation Effects on Buried Pipelines written by Dimitra Bouziou and published by . This book was released on 2015 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary subject of this thesis is the evaluation of pipeline performance during earthquakes through analytical and experimental studies, spatial analysis, and probabilistic methodologies. Permanent ground deformations caused by liquefaction are also addressed through spatial and statistical analysis, and are compared to foundation deformations caused by liquefaction effects estimated through building damage surveys. This thesis starts with a comprehensive analytical and experimental assessment of segmented pipeline response to transient ground deformation before and after rehabilitation with in situ lining technologies. The different modes of segmented pipeline deformation caused by seismic wave propagation are investigated through finite element analyses to show that the most prominent form of deformation at weak pipeline joints and circumferential pipe cracks are in the axial direction. They exceed the levels of all other forms of pipeline deformation by several orders of magnitude. Nonaxial deformations have negligible effects on pipeline performance under seismic body wave propagation. Pipeline performance after rehabilitation with in situ linings is studied through large-scale testing and the effectiveness of in situ lining technology for seismic retrofit of critical lifelines is evaluated. Pipeline performance during earthquakes is also investigated through spatial analysis of the Christchurch water distribution system response to transient and permanent ground deformations during the 22 February 2011 Christchurch earthquake, New Zealand (NZ). Repair regressions for different pipe types are developed using spatial data sets that are unique in size and complexity, including dense array ground motion records, detailed mapping of areas affected by soil liquefaction, as well as spatial data sets for the water distribution system, geocoded repair records, and high resolution Light Detection and Ranging (LiDAR) measurements of vertical and horizontal movements. This study expands on previous work in several important ways, and provides a detailed framework of the analytical processes for repair regressions that assists in future investigations with data of similar size and complexity. A probabilistic model is presented in which the expected value of the ground strain in the axial pipeline direction within a strain field is calculated by assuming that pipeline orientation with respect to the strain field is uniformly distributed and by accounting for possible differences in tensile and compressive strains with a weighting factor. The proposed methodology is applied in regression analysis of pipeline damage caused by lateral ground strains during the 22 February 2011 Christchurch earthquake, NZ, and can be used for future investigations to improve the assessment of ground strains affecting segmented pipelines. Permanent ground deformation during the 2010-2011 Canterbury Earthquake Sequence, NZ, is evaluated through statistical analysis of vertical and lateral ground displacements, as well as differential vertical displacements and lateral ground strains, calculated from high resolution LiDAR surveys. Ground deformation patterns are identified with respect to topographic characteristics through the use of LiDAR ground displacement measurements. Foundation deformations caused by liquefaction effects are estimated using damage survey data in residential properties in Christchurch and are evaluated with respect to liquefaction-induced ground deformations.

Download or read book Measuring Liquefaction induced Deformation from Optical Satellite Imagery written by Jonathan Grant Martin and published by . This book was released on 2014 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction-induced deformations associated with lateral spreading represent a significant hazard that can cause substantial damage during earthquakes. The ability to accurately predict lateral-spreading displacement is hampered by a lack of field data from previous earthquakes. Remote sensing via optical image correlation can fill this gap and provide data regarding liquefaction-induced lateral spreading displacements. In this thesis, deformations from three earthquakes (2010 Darfield, February 2011 Christchurch, and 2011 Tohoku Earthquakes) are measured using optical image correlation applied to 0.5-m resolution satellite imagery. The resulting deformations from optical image correlation are compared to the geologic conditions, as well as field observations and measurements of liquefaction. Measurements from optical image correlation are found to have a precision within 0.40 m in all three cases, and results agree well with field measurements.
