Numerical Study on Cyclic Loading Effects on the Undrained Response of Silty Sand
https://orcid.org/https://orcid.org/0000-0002-0514-0841
The soil liquefaction is a major earthquake disaster which causes tremendous damages to all infrastructure facilities. The examples during past earthquakes have shown the evidence of liquefaction-induced ground failures in fine-grained soils. Until recently, liquefaction-related studies concentrated on clean sands believing that only sands are susceptible to liquefaction. However, the earthquakes like 1976 Tangshan earthquake, the 1989 Loma Prieta earthquake, the 1999 Kocaeli earthquake, the 2010 Chile earthquake, and the 2011 Christchurch earthquake, etc., showed that sand with fines could also liquefy. The present study deals with the numerical simulations on cycling loading effects on the undrained response of silty sand. The material parameters for the numerical model are found after conducting basic experimental tests. The response of silt sand under the undrained condition of cyclic triaxial loading is analyzed using the hypoplastic constitutive model. The influence of soil parameters, i.e., void ratio/relative density and consolidation pressure level on undrained response of soil is examined from model simulations.
