Therefore, the traditional cut and cover method is gradually not acceptable method for the underground pipeline construction. Instead, No-dig methods are getting popular as they can avoid the problems of traffic congestion, noise and pollution. In this study, finite element software ABAQUS/Standard is apply to simulate the construction of pipe jacking, by taking account of the contact between pipe and soil in order to analysis the interaction in pipe jacking. The numerical analysis includes both physical model and curve pipe jacking. In the simulation of physical model both overcut and undercut is considered, the result of those model are compared with the experiment data. In the simulation of curve pipe jacking, establish displacement at outer the out edge, as well as the effect of grouting is studied. Based on the results of stress distribution and surface settlement, suggestions can be feedbacked to really designs.
