This course on Geotechnical Earthquake Engineering introduces the fundamental concepts of earthquake engineering related to geotechnical problems, principles of earthquake, wave propagation, dynamic soil properties, liquefaction and seismic design of various geotechnical structures. This course focuses on seismic hazard analysis which includes both Probabilistic Seismic Hazard Analysis (PSHA) and Deterministic Seismic Hazard Analysis (DSHA), followed by site response analysis. Also, behaviour of various geotechnical structures such as shallow and deep foundations, retaining structures, slopes, ground anchors, waterfront retaining structures, reinforced soil-wall, tailing dam due to earthquake loading are discussed with reference to codal provisions. The course material on Geotechnical Earthquake Engineering will be very useful to the post-graduate students, researchers, teachers and practitioners. A number of selected problems will be solved to illustrate the concepts clearly.
