摘　　要：通过对两种不同砂土的试验 ,讨论了低密度饱和砂土试样的固结不排水剪切试验方法及由试验得到的结果提出的应变软化模型及稳态强度 ,并对试验所得结果及提出的模型用于堤坝及地基地震后稳定分析提出建议 .By means of experiments of two kinds of sandy soils, the method of consolidated-undrained triaxial test on loose saturated sand sample as well as the strain-softening model and the steady strength obtained from the test results are discussed in this paper. The application of experimental results and the models for post-earthquake analysis of embankment and its foundation is also suggested.

关 键 词：稳态强度 应变软化 振动孔压 砂土 强度试验
