Methods for evaluating the seismic isolation performance of foam concrete shock-absorbing layers in mountain tunnels in high-seismic-intensity areas

Currently, a large number of post-earthquake surveys and statistical analyses of tunnel damage indicate that tunnels built against mountainsides are subject to the coupled effects of “asymmetric loads and seismic cyclic action,” which increase the risk of earthquake-induced damage to these tunnels. Therefore, the pri...
