| 摘 要： | 影响基坑基底隆起的因素存在极大的模糊性和随机性,基底隆起变形量的计算是一个复杂的非线性过程,而采用有限元法对基坑基底隆起变形量进行分析是个有效的途径。本文以上海某深基坑为例,基于ABAQU S软件对该基坑基底隆起变形量进行有限元分析。研究表明,基底隆起最大变形量发生在离基坑侧壁约以SMW围护桩入土深度为半径的圆内侧。本文将为基坑隆起问题的定量研究提供有价值的参考。 |
| 关 键 词： | 岩土工程 深基坑 抗隆起变形量 SMW围护桩 |

| Abstract: | It is a complicated nonlinear procedure to calculate the deformation against upheaval of deep foundation pit,because the factors affecting the deformation are fuzzy and random.However,the finite element analysis is an effective method to solve the problem.Based on the finite element software ABAQUS,in this paper,the heave deformation of deep foundation pit for some subway in Shanghai is analyzed.The study shows that ABAQUS has powerful capacity to analyze the contact problems in geotechnical engineering,and the Maximum deformation appears in a certain region which is not beyond the circle with radius equal to the depth of SMW pile from the wall of the deep foundation pit.The study can provide valuable reference for quantitative heave analysis for deep foundation pit. |
| Keywords: | geotechnical engineering deep foundation pit deformation against upheaval SMW retaining piles |
