Influence of Buried Depth on Seismic Responses of Water-Conveyance Tunnel Concrete Lining

Abstract:

The paper is combined by the 2^nd phase engineering of Dahuofang water-conveyance tunnel. The 3D finite element models of the circular tunnel were built to analyze the seismic responses of the concrete lining under homogeneous rocks and nonhomogeneous rocks. The stress distribution of the concrete lining was studied under different buried depths. The results show that the seismic responses of the concrete lining magnify first and then reduce with the increase of the buried depth. The maximum stresses appear when the buried depth is up to 25m. It affords an important engineering reference for tunnel site selection, design and construction.
