In order to explain macroscopical deformation of saturated soft clay under subway load,the cyclic triaxial test,mercury intrusion porosimetry(MIP) and scanning electron microscopy(SEM) are conducted and the correlatability between microstructure change and macroscopical deformation of saturated soft is analyzed.

In the paper,the dynamic elastic modulus of soil is determined by laboratory dynamic triaxial tests,and the deformation of soil around subway tunnel under subway vibrational loading is computed with numerical simulation,then,the ground subsidence induce.

After the subway tunnel that is in or across the stratum of saturated soft clay is put to use,the excessive settlement occurs along axes in a large degree because the microscopic structure of the saturated soft clay is deformed and destroyed and the residual strain is produced under the subway vibrational loading.

Sweden slice method and FLAC/SLOPE were applied in a mountain electric substation slope stability analysis,to explore the iron tower load s influence on slope stability,and calculation results of two methods were compared and analyzed.
