Abstract

Abstract

The initial geostress and seepage field are destroyed because of tunnel excavation. Take circular tunnel for example,the distribution of stress field, pore water pressure and displacement field after tunnel excavation will be obtained with Finite-difference procedures considering seepage force. Meanwhile, the difference of displacement field is contrasted between whether or not take into account seepage effect and also the different distribution of displacement field under diverse water line. Eventually, the relative suggestion of waterproof and drainage, design and construction on tunnel is provided.
