为了深入研究软土在移动地铁荷载作用下产生的软化现象，对南京软土进行室内GDS 动三轴试验。采用初始动剪切模量计算公式对南京软土进行计算和比较分析，建立考虑频率影响因素的经验计算公式。同时提出考虑振动次数的动剪切模量函数计算公式，对南京软土进行计算和分析，并用不同地区的土验证公式适用性。结果表明：考虑频率影响因素的初始动剪切模量计算公式能更准确地计算初始动剪切模量，提出的考虑振动次数的动剪切模量函数计算公式对不同地区土的适用性较好。

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.
