角位移

Analyzed on the tunnels that used EPB method in different soils, the more logical three-dimensional finite element model is based, which can reality represented the soil transfiguration. 3 Due to the engineering example, a 3D FEM simulation model was founded. The model was used to study the rules of soil deformation and surface settlement during shield tunneling. 4 The characteristics of loess include the module, conglutination force and inner friction angle of the loess, affected the soil deformation. 5 The influence factors to the surface settlements such as the depth of soil, the outer diameter of the shield tunnel, the released stress at the cutting face, the fill ratio of the shield tail void, pouring-slurry press, thrusts and lengths of shield and digging steps were studied using the FEM method. References is brought forward in the loess areas of Xi'an was proposed.
