| 摘 要： | 用二维有限元法计算了墙面桩在6种典型工况下的弯矩及位移、锚定桩与围岩的接触应力及位移、填土沉降及土压力和锚索内力等，计算结果与原型观测和弹性约束地基系数法等的结果基本一致．计算结果表明。预应力锚索能有效地减小墙面桩的弯矩及位移．

| Abstract: | With 2-D finite element method (FEM), the moment and displacement of metope pil es, the stress and displacement of interface between anchorage pile and surround ing rock, the settlement and earth pressure of filling soil, and the internal fo rce of anchored cables are calculated in six typical conditions of construction. And the calculation results accord basically with those of field observation an d other numerical methods. The results show that the the moment and displacement of metope piles can be decreased effectively by the use of prestressed cables. |
