摘要：In this paper, how to determine the soil parameters and initial values employed in the numerical calculation using experimental results is talked over in detail. The results of the triaxial compression tests and one-dimensional tests for undisturbed and disturbed samples are utilized step by step to modify the numerical results. It is found that there are several steps to model the whole procedure of sampling from the ground to the experiment equipment. Therefore, the step of taking the soil samples out from underground, which is assumed to be under the undrained condition accompanying with unloading process until the deviator stress becomes zero, is always ignored in the research.
