Experimental Study on the Dynamic Characteristics of Shanghai Soft Clay Subjected to Cyclic Loading
摘要
Abstract
To study the strength of Shanghai soft clay under cyclic loading,a series of dynamic triaxial tests were conducted with different dynamic stress ratios and frequencies.According to the test results,the relationship between the shear modulus and strain was not affected by the dynamic stress ratio and frequency.When the strain was set to 2%,the shear modulus decreased slowly but significantly.The sample cyclic time with high frequency was larger than that with low frequency.With the Shanghai soft clay,soil sample damage phenomenon occurred until the dynamic stress ratio reached 0.2.The frequency had different effects on the growth of the strain in different strain stages.关键词
