Download or read book Liquefaction induced Lateral Displacements from the Canterbury Earthquake Sequence in New Zealand Measured from Remote Sensing Techniques written by Sorin S. 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 Factors Influencing the Lateral Spread Displacement from the 2011 Christchurch New Zealand Earthquake written by Olivia Catherine Deterling and published by . 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.

Book excerpt: The 4th International Conference on Performance-based Design in Earthquake Geotechnical Engineering (PBD-IV) is held in Beijing, China. The PBD-IV Conference is organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering - Technical Committee TC203 on Earthquake Geotechnical Engineering and Associated Problems (ISSMGE-TC203). The PBD-I, PBD-II, and PBD-III events in Japan (2009), Italy (2012), and Canada (2017) respectively, were highly successful events for the international earthquake geotechnical engineering community. The PBD events have been excellent companions to the International Conference on Earthquake Geotechnical Engineering (ICEGE) series that TC203 has held in Japan (1995), Portugal (1999), USA (2004), Greece (2007), Chile (2011), New Zealand (2015), and Italy (2019). The goal of PBD-IV is to provide an open forum for delegates to interact with their international colleagues and advance performance-based design research and practices for earthquake geotechnical engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the application of a comparatively simple nonparametric regression algorithm, known as the multivariate adaptive regression splines (MARS) surrogate model, which can be used to approximate the relationship between the inputs and outputs, and express that relationship mathematically. The book first describes the MARS algorithm, then highlights a number of geotechnical applications with multivariate big data sets to explore the approach’s generalization capabilities and accuracy. As such, it offers a valuable resource for all geotechnical researchers, engineers, and general readers interested in big data analysis.

This book was released on 2019 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquake induced soil liquefaction has been one of the most studied topics in geotechnical engineering over the past 60 years due to its severe impacts on natural and man-made structures. Improving the prediction of liquefaction triggering has already been undertaken for many years, however, in ways that can produce inconsistent, and inaccurate, results in different seismic environments. The first focal point of this thesis is the introduction of a liquefaction-targeted intensity measure that would allow practicing engineers to obtain the benefits of a full probabilistic liquefaction hazard analysis with the same, or less, effort than required by current conventional liquefaction hazard analyses. Lateral spreading is one of the most common, and most severe, effects of liquefaction. Up to three mechanisms are believed to drive lateral spreading. Each of these potential deformation mechanisms is influenced by static shear stresses yet both empirical and semi-empirical procedures for prediction of lateral spreading displacements currently characterize static shear stresses in a crude and incomplete manner. The second focal point of this research was directed toward developing an improved framework for characterizing the initial static shear stresses over a continuous range of site conditions commonly encountered at lateral spreading sites. This framework is intended to lay the foundation for an improved lateral spreading displacement procedure. To accomplish this, numerical analyses were performed to develop a function that can predict the initial static shear stress at depths of lateral spreading interest.
