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.

通过对不同土质条件下盾构法进行地铁隧道施工的有限元分析，全面反映盾构推进对土体变形的影响情况； 3根据有关勘测资料，建立合理的盾构法施工三维非线性有限元模型，对盾构法施工引起的地层变位和地表位移情况进行计算，分析了盾构施工引起的地层变形规律和地面沉降规律； 4研究了黄土特性(地基模量、粘聚力和内摩擦角)对盾构法施工中土体变形的影响； 5利用三维有限元对盾构施工过程中影响地面沉降的因素(覆土厚度、隧道外径、开挖面压力变化量、注浆压力、盾尾空隙填充率、开挖步长、盾构机的长度和推进力等)进行研究，为今后西安地区地铁的建设提供参考。

The result showed that,if only the necessary but insufficient condition,the equilibrium condition ,was adopted to deal with the infinite uncertain boundary condition,the solution to the stress was non-unique due to the fact that the boundary problem here was a mal posed mathematic problem.

通过两个典型的半无限体实例，对水平表面作用无限均布压力下弹性地基的应力和位移解答进行研究，结果表明：对边界条件不明确的无限边界仅采用解答的必要非充分条件——平衡条件来等效处理，其应力解答不是唯一的，因为此时该边值问题不是一个适定的数学问题。
