【 摘 要 】

By collecting and sorting the thermal physical indexes of the 1, 2, 5, 7 and 11 lines of Shenzhen metro, the relationship between the physical properties and the physical properties of gravel clay was analyzed. The correlation statistics of factors affecting the thermal physical indexes of gravel clay are carried out. The empirical formula of specific heat capacity and heat conductivity are proposed on the basis of moisture content, void ratio and density. It provides a new way to obtain the thermal physical indexes in the investigation and design of the subway engineering.
