Through the investigation of the seismic damage to the tunnels by the Wenchuan Earthquake on May 12, 2008, the damage mainly takes the following forms:tunnel lining shear location movement, the tunnel structure destruction caused by the slope destruction, tunnel lining destruction, side wall destruction and tunnel portal collapse. It is closely related to the earthquake magnitude, the earthquake intensity,...
Frequent earthquakes cause severe damage to some underground structure at present. The existing aseismic norms about underground tunnel become too briefly, which can not adapt to the development of constructing of tunnel in high intensity areas. So, the aseismic study of underground structure is in urgent demands. Of the study, the numerical analysis and processing of seismic wave is very important...
With the frequent occurrence of earthquakes, which cause severe damage to some underground structure, the existing domestic and international aseismic norms about underground caverns become too briefly, which can not adapt to the development of underground tunnels in high intensity earthquake areas. Now, our aseismic study of expressway tunnel is in urgent need. Combining with the project of aseismic...
