摘要
不同的埋深条件下,隧道结构的地震响应差别很大,但其影响规律和特点目前尚停留在震害调查和经验认识的阶段,尚缺乏系统的分析和研究.采用FLAC3D软件,以勒不果喇吉隧道为例,运用数值分析方法对不同埋深条件下的隧道结构地震响应进行数值计算和分析,总结出其基本影响规律和特点,并提出了临界埋深的概念.
Under different depth conditions,the seismic response of the tunnel varies widely,but its currentregularity and character remain in the phase of damage investigation and experience, lacking of systematic analysis and research. With the help of FLAC3D software, based on the example of LEBUGUOLAJI tunnel, we analyze the seismic response of tunnel structure under different depth conditions using numerical analysis. Then we sum up the basic rules and character and put forward the concept of critical depth.
