| 摘 要： | 根据深基坑土钉支护的受力特点 ,土钉与土体粘结滑移的工作性能 ,以及实际工程中的开挖建造与锚杆预应力施加等一系列施工过程 ,编制了针对锚杆 -土钉复合支护的三维非线性有限元程序 ,重点讨论了锚杆的存在对坑壁变形与土钉内力的影响。分析结果表明在对变形要求较严时 ,使用锚杆 -土钉复合支护可以有效控制变形。

| Abstract: | A 3\|D nonlinear finite element program is drawn up herein for the composite bracing of anchor rods with soil nail based on characteristics of bracing by soil nail, the working behaviours of nail with soil and the excavation and construction process. Discussion is stressed on the influences of existing ahchor rods on the deformation of pit wall and that on the internal force of soil nail. The results indicate that the composite bracing of anchor rods with soil nail may control the deformation effectively. |
