摘要
为深入研究开挖深度不同情况下深基坑支护结构的变形和内力,运用岩土工程二维有限元软件PLAXIS进行此类深基坑开挖全过程的模拟。通过不同工况的模拟及计算,结果表明由于基坑开挖深度的不同,基坑两侧支护结构的水平位移和内力均有较大差异,在基坑设计中有必要对基坑的支护结构进行优化设计。
In order to study the deformation and the internal force of retaining structures of deep foundation pits under different excavation depths,PLAXIS is adopted to simulate the whole process of deep excavation.Through various simulations and calculations on the excavation depth,the analytical results show that the deformation and the internal force of retaining structures at the both sides of the foundation pits largely change with the excavation depth.So,it is necessary to optimize the design of retaining structures of deep foundation pits.
