Impact of Changes in Matric Suction on Dynamic Properties of Unsaturated Silty Soil from Small to Large Strain During Drying Path, M.Sc. Thesis Sharif University of Technology ; Haeri, Mohsen (Supervisor) ; Khosravi, Ali (Supervisor)
Abstract
Shear modulus and damping ratio are of the most important parameters for geotechnical structures during dynamic and seismic loading. Secant shear modulus is the slope of hysteresis shear stress-shear strain loop, and damping ratio is indicative of dissipation of waves energy during propagation in the soil. These parameters mainly depend on void ratio, stress state, and shear strain of the soil. Climate changes cause some drying and wetting process which changes the soil state from saturated to unsaturated form. Previous researches indicated that the shear modulus and damping ratio change with the amount of matric suction. During the drying process, the matric suction increases,therefore,...
