Being taken into account the nonlinearity of soil,the interaction of soil and shield tunnel, grouting pressure,jack thrust pressure and airlock earth pressure to establish a three dimensional nonlinear finite element model was established by using the finite element program Midas / GTS. The influence on the surface settlement of adjacent surface structures and shield tunneling was studied. The result shows that the maximum settlement value with structure is smaller than which without structure; the maximum settlement value is on the opposite direction of the structure,and deviates from the central axis of the shield; the closer to the lateral earth pressure at rest the shield support pressure is,the smaller the surface subsidence will be; reasonable control shield tunnel parameters( grouting pressure,jack thrust) can effectively reduce surface settlement.
