Lateral Seismic Response Analysis of Shield Tunnel Structure
The dynamic time-history method is one of the methods with high accuracy to analyze the seismic response of the shield tunnel structure. However, it is hard to apply in engineering practice for complex boundary conditions and nonlinear constitutive. This paper has derived the analytical solution of internal force of the structure with the soil-circular tunnel in no slip. The internal force and displacement of Suai shield tunnel structure has been calculated by PROSHAKE and ABAQUS under the action of artificial wave and Iwate wave. It can be shown that the distribution of internal force in different position of analytic solution is similar to the numerical solution after comparation. Though the internal force peak value of numerical solution is larger than analytic solution, the relative error in different case is less than 10%. It can meet the requirement of accuracy in engineering and prove a simple algorithm for the analysis of lateral seismic response.
