Available in PDF, EPUB and Kindle. Book excerpt: This book presents comprehensive hazard analysis methods for seismic soil liquefaction, providing an update on soil liquefaction by systematically reviewing the phenomenon’s occurrence since the beginning of this century. It also puts forward a range of advanced research methods including in-situ tests, laboratory studies, physical model tests, numerical simulation, and performance-based assessment. Recent seismic liquefaction-related damage to soils and foundations demonstrate the increasing need for the comprehensive hazard analysis of seismic soil liquefaction in order to mitigate this damage and protect human lives. As such the book addresses the comprehensive hazard analysis of seismic soil liquefaction, including factors such as macroscopic characteristics, evaluating the liquefaction potential, dynamic characteristics and deformation processes, providing reliable evaluation results for liquefaction potential and deformation in the context of risk assessment. “p>

Available in PDF, EPUB and Kindle. Book excerpt: Liquefaction has caused significant failures and represents a significant problem for the community and geotechnical engineering designers (Pyrah et al., 1998). However, in practice, a single reliable method for assessing the liquefaction potential of soils is not well defined, particularly for aged soils. This is due mainly to the fact that most research has been based on 'clean sand' as the calibration to define the boundary between liquefaction and non liquefaction behaviour. Therefore, a well defined procedure for liquefaction assessment which is applicable to soils of any age is a crucial first step in reducing the risk of substructure failures and mitigating casualties resulting from earthquakes. The research presented herein is focused on investigating the capability of the cone penetration test (CPT) and flat dilatometer test (DMT) for liquefaction assessment on natural soils considering soils deposited more than 1100 years ago at Gillman, South Australia. The recommended CPT procedure from the 1996 NCEER and 1998 NCEER/NSF Workshops is employed. In addition, the age correction factor proposed by Hayati et al. (2008) is used to revise the cone resistance ratio (CRR) values obtained from the NCEER/NSF procedure. The DMT procedure is selected as another contender in this liquefaction assessment because some researchers, such as Yu et al. (1997), Sladen (1989) and Marchetti (1999), claimed that the DMT is able to capture the ageing effect of the soils. Extensive study to define the peak ground acceleration for this liquefaction assessment is conducted by using one-dimensional, site-specific ground response analysis (SHAKE91 and EERA). The most recent and significant natural earthquake motions recorded by two separate accelerogram stations are obtained and manipulated to suit the data entry format of the response analysis methods. The soil unit weight and its shear wave velocity are derived from CPT and DMT data by using several empirical correlations. The results are then applied individually to each procedure. The critical state approach for liquefaction assessment introduced by Jefferies & Been (2006) is used to verify the assessment of both the CPT and DMT procedures. The simple critical state parameter test proposed by Santamarina & Cho (2003) is undertaken on 6 soil samples taken from the study site to estimate the in-situ state parameter. Liquefaction assessment using the CPT data incorporating ageing and DMT procedures (i.e. Marchetti, 1982 and Monaco et al., 2005) are presented and a comparison between all procedures is carried out. Re-examination using critical state approach is made. In addition, the consequences of the liquefaction in terms of ground settlement are also investigated. Finally, this study shows that soil ageing increases the ability of soil to resist during the seismic loading. Furthermore, by assuming that the critical state approach represents the true conditions of the study site, the liquefaction assessment method proposed by Marchetti (1982) from DMT data provides better prediction than the others.

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.

Available in PDF, EPUB and Kindle. Book excerpt: In Situ Testing Methods in Geotechnical Engineering covers the field of applied geotechnical engineering related to the use of in situ testing of soils to determine soil properties and parameters for geotechnical design. It provides an overview of the practical aspects of the most routine and common test methods, as well as test methods that engineers may wish to include on specific projects. It is suited for a graduate-level course on field testing of soils and will also aid practicing engineers. Test procedures for determining in situ lateral stress, strength, and stiffness properties of soils are examined, as is the determination of stress history and rate of consolidation. Readers will be introduced to various approaches to geotechnical design of shallow and deep foundations using in situ tests. Importantly, the text discusses the potential advantages and disadvantages of using in situ tests.

Available in PDF, EPUB and Kindle. Book excerpt: Demanding a thorough knowledge of material behaviour and numerical modelling, site characterisation and in situ test interpretation are no longer just basic empirical recommendations. Giving a critical appraisal of the understanding and assessment of the stress-strain-time and strength characteristics of geomaterials, this book explores new interpretation methods for measuring properties of a variety of soil formations. Emphasis is given to the five most commonly encountered in situ test techniques: standard penetration tests cone penetration tests vane test pressuremeter tests dilatometer tests Ideal for practising engineers in the fields of geomechanics and environmental engineering, this book solves numerous common problems in site characterisation. It is also a valuable companion for students coming to the end of their engineering courses and looking to work in this sector.
