Abstract

This document is based on the gravel test subgrade paved at the K3012 of the Qinghai-Tibet Highway near the Wudaoliang section, a large finite element software Abaqus is used to simulate the temperature field of gravel subgrade, and the influence of the particle size temperature field is obtained. The results show that both the 2-4cm and the 10-15cm gravel subgrade can protect the permafrost under the roadbed well, but the gravel subgrade with 6-8cm diameter is lower than that, which is more favorable to the stability of permafrost.
