Dynamic Characteristics of Soft Clay Under Traffic Load

The widely distributed soft clay in Shanghai is particularly prone to settlement, causing many disasters. In order to predict the settlement of soft soil, an in-house dynamic triaxial test was carried out to study the influence of dynamic stress amplitude, frequency and effective average principal stress on the axial strain of soft soil. It laid the foundation for the study of settlement of soft clay in Shanghai. This article also put forward many places worth considering and investigating and hoped to help scholars.
