STUDY ON WATER ABSORPTION AND THERMAL CONDUCTIVITY OF TUNNEL INSULATION MATERIALS IN A COLD REGION UNDER FREEZE-THAW CONDITIONS

Study on Water Absorption and Thermal Conductivity of Tunnel Insulation Materials in a Cold Region under Freeze-Thaw Conditions

A thermal insulation layer is often deposited on the lining structure of tunnels in cold regions to solve the problem of frost damage.When the air humidity in the tunnel becomes excessively high, the thermal insulation material tends to absorb water, leading to Delta Edible significant changes in thermal conductivity.Moreover, the temperature diffe
