Experimental research on parameter selection of HSS model for Ningbo shallow soft soil

The small strain hardening soil model (HSS model) is widely used in numerical analysis because it can consider the small strain characteristics of soil, and the numerical simulation results are usually closer to the measured values. At present, the researches on the HSS model parameters of soft soil are mainly concentrated in Shanghai, and the research results in other areas are less. The HSS model parameters of shallow soft soil in Ningbo area are studied through indoor tests, and compared with the statistical results of the existing literatures. The results show that most of the HSS model parameters are within the statistical range, indicating that the Ningbo shallow soft soil has its commonness with that in other areas. The test values of some parameters are not within the statistical range, indicating that the Ningbo shallow soft soil also has its regional differences.
