Abstract

Since earthquake hazards are seriously threatening economy and sustainable development, it is particularly significant to study the seismic analysis of large-diameter shield tunnels in regions with high seismic intensity to ensure the seismic safety of the tunnels. This study is based on an overseas large-diameter shield tunnel project as a background in which the normative response spectrum was obtained according to Chinese codes and local codes. According to the selected 6 effective seismic waves, the dynamic time history analysis method was applied to select the typical cross section of the longitudinal tunnel section. A two-dimensional finite element model was established for the surrounding soil to analyze the overall force and deformation of the shield tunnel under the action of the earthquake, internal force of the tunnel rings and uneven settlement etc., in order to analyze the rationality and feasibility of the design.
