| 摘 要： | 在对基坑开挖的有限元模拟中,土体刚度矩阵、外荷载和开挖荷载等都随开挖深度的变化而变化。刚度矩阵采用空气单元方法处理,开挖荷载采用Mana方法计算。算例分析结果表明,随着深度加大,最大水平位移的位置由边坡内部移至坡面上,而坑底隆起减小。 |
| 关 键 词： | 深基坑 开挖 支护 有限元数值模拟方法 |

| Abstract: | In the finite element simulation of foundation pit excavation,the stiffness matrix of soil,the external loads and the excavation load are changed with the increasing depth.The air element method is used in the stiffness matrix calculation,and the Mana method is adopted to calculate the excavation load.The analysis results of an example show that the site of maximum horizontal displacement transfers from the interior to the face of the side slope with the increasing depth,while the upheaval of the pit bottom decreases. |
| Keywords: | deep foundation pit excavation supporting numerical simulation FEM |
