In order to study the thermal insulation and shock absorption performance of two kinds of thermal insulation materi- als？with the JI Wo XI GA Tunnel of the Lasa-Rikase Railway as an illustrative example^the finite difference numerical simula-tion technique is used to analyze the thermal insulation and shock absorption effects of two kinds of thermal insulation materi-als the silicate adiabatic composite felt and the rigid polyurethane board. The research result shows that the temperature of the secondary lining structure is somewhat reduced after either of the two kinds of thermal insulation materials is applied？with the best position for the thermal insulation effect being at the inverted arch of the tunnel. As far as the thermal insulation effect is concerned,the thermal insulation effect of the silicate adiabatic composite felt is 5. 110 %, and that of the rigid polyurethane board is 6. 282%. The safety factor of the secondary lining structure is increased to some extent after either of the two kinds of thermal insulation materials is applied. The shock absorption effect is obvious at both the vault and the inverted arch,but the increase in the damping effect of the other monitoring points is limited？ so the overall damping effect is just so so. The research results may serve as technical support for the thermal insulation and shock absorption design for high-rock-temperature tunnels in meizoseismal areas.
