This offers a comprehensive and insightful guide to the analysis and design of earth retaining structures, with a particular focus on their behaviour under seismic loading conditions and soil and structure interaction. It combines principles with practice, and relates the behaviour of earth retaining systems to the fundamental principles of soil mechanics and the methodologies of limit states design. The design approach is modern and rigorous. The book’s innovative and original methods for seismic analysis and application to practical engineering problems satisfy the increased need for earthquake-resistant geotechnical design. This is primarily a textbook for graduate students in civil and geotechnical engineering, and also a reference for practising engineers to update and refine their design skills, particularly in relation to seismic performance and modern design standards.
