Abstract
In order to realize the seismic response analysis of the parallel double-hole tunnel, this paper takes the double-hole tunnel of an underground section of shenyang subway as the research object, USES midas-gts to establish a three-dimensional finite element numerical calculation model, and analyzes and discusses its seismic response. The results show that:Under the action of seismic wave, the maximum position of relative displacement of soil is usually at the soil boundary, and the maximum position of relative displacement of tunnel lining is usually at the tunnel entrance. Along the input direction of seismic wave, the maximum relative displacement of the tunnel is greater than the corresponding value of the other two directions.
