摘要：

The paper deals with analysis of the dynamic response of the rock surrounding tunnels during earthquakes. The analysis presented illustrates the effect of the dynamic loads on the stability of tunnels. It is concluded that the stresses induced by earthquakes are usually much smaller than the strength of the rock that surrounds the tunnel. Generally, funnels have a fairly high safety against earthquakes. However, at the earth surface the reaction to the earthquake action may lead to more complicated consequences. The proposed approach can also be used for estimation of dynamic load influence on development of stress and displacement fields around tunnels. For the purpose of the analysis modification in the numerical program FLAC were introduced The improvement allows for more suitable boundary conditions that match the dynamic process.
