摘要
通过二维和三维有限元计算了顶管施工产生的土体变形和土体应力。通过对机头土压力、摩阻力和机头的偏斜几种因素的分别计算,探讨了这几个因素对地表变形的影响,得出了一些有益的结论。
The deformation and stresses of soil by pipe-jacking are calculated with 2D and 3D finite element methods. The calculations considere three factors independently,that is,the soil press on the head of pipe-jacking,friction in soil and deviation of pipe-jacking head. Their influence on earth surface deformation are examined and some useful conclusoions are drawn.
