摘要：

To research soft clay softening induced by moving metros load, an indoor GDS dynamic triaxial test on Nanjing soft clay was carried out. The computational formula with the original dynamic shear modulus was used to calculate and analyze the Nanjing soft clay. And an empirical formula considering the frequency factor was established. Meanwhile, a function considering the vibration number for the dynamic shear modulus was presented to calculate and analyze the Nanjing soft clay and the applicability was verified by testing on clay from different regions. It is shown that the original dynamic shear modulus formula considering the frequency factor can be accurately determined and the dynamic shear modulus function considering the vibration number has a good applicability to the clay from different regions. ©, 2015, Northeastern University.
