Abstract: In order to improve seismic safety of the tunnel with high rock temperature in meizoseismal area, this paper studied the rigid and flexible compound disaster reduction technology by finite difference software based on a research of Jiwoxiga tunnel on the Lasa-Rikase railway. And the results show that the damping effect and thermal insulation effect of tunnel structure are 40.91% and 1.4% respectively if only shock absorption layer is laid; the antiseismic effect and heat resistance effect of tunnel structure are 46.39% and 1.9% respectively if only interval injection of surrounding rock is taken and the pressure of surrounding rocks on secondary lining structure is reduced; the anti-seismic and damping effect, heat resistance or isolation effect of tunnel structure are 63.38% and 2.7% respectively if full-ring interval injection of surrounding rock is conducted and shock absorption layer is laid. The disaster reduction effect of the rigid and flexible compound technology is the best.
