“…For example, an automobile is running on the roadbed at a certain speed. Based on experimental data, the characteristics of rock and soil are random with a boundary infinite element (Chen et al, 1993;Hao et al, 2001;Cascetta et al, 2016;Liu et al, 2018). The analysis of dynamic randomness, which exists in any structure, is a task that must be studied now.…”

In view of the problems of a single parameter of rock and soil materials, unclear boundary simulation and a simplified dynamic load in the current calculation of pavement settlement, the stochastic finite element-infinite element coupling method was adopted in this study to simulate the roadbed of rock and soil, with a dynamic response analysis and a flexible pavement settlement calculation of roadbed were carried out under stochastic dynamic load. Discrete methods and dynamic stochastic finite element formulas for rock and soil random fields were particularly dealt with in this study. The results show that the method to stimulate roadbed is true with high calculation accuracy and strong engineering guiding significance. The displacement of flexible ground at any depth can be obtained by calculating the settlement of flexible pavement with the aid of the Matlab computer program.
