Research on partial pressure joint arch tunnel's dynamic simulation and optimum analysis of construction process

Junwei Li

Abstract

In order to simulate and make optimum analysis of partial pressure joint arch tunnel, a 3D finite element model is established.The simulation results are compared with the measured data in site.Arch crown settlement, stress and displacement of middle wall, plastic area distribution of surrounding rock, and variation of initial and secondary linings are analyzed.Then, the joint arch tunnel's optimal construction sequence, the optimal construction space of two holes, the suitable construction method of cutting face and cycle length are determined by the simulation.The results provide a scientific basis and technical guidance for the construction optimization of partial pressure joint arch tunnel.
