Assessment of Effectivness of Compaction Improvement for Liquefaction Mitigation of Saturated Sand Deposits Based on Performance Levels of Shallow Foundations, Ph.D. Dissertation Sharif University of Technology ; Pak, Ali (Supervisor) ; Ghannad, Mohammad Ali (Supervisor)
Abstract
Settlement and tilt of structures due to liquefaction of subsoil layers is a major cause of damage during earthquake. One of the main approaches to reduce terrible effects of liquefaction on shallow foundations is ground improvement. Among the variety of ground improvement methods, the densification-based methods have been more paid attention for liquefaction mitigation. For liquefaction hazard mitigation using densification methods, three basic values should be determined i.e. depth, lateral extent, and degree of improvement (percent increase in Dr). In the current design practice, the need for ground improvement is usually decided based on the semi-empirical methods for assessment of...
