In order to research the correlation between soil thermophvsical indexes and value of CPT, this article collected he geotechnical thermophysical indexes of several subway tunnels in Shanghai coastal plain. The research found that the thermal conductivity and thermal conductivity increased with the increasing of value of CPT, the specific heat capacity decreased with the increasing of value of CPT in the soil static cone penetration test. Which shows a certain regularity. Using the curve fitting of thermophysical index and static cone penetration test PS value, it is found that thermophysical index and static cone penetration test PS value can be calculated mutually through specific formula.
