摘要
在开发利用地下空间过程中遇到了许多棘手的问题,由于受环境和规划选址的限制而使得基坑两侧围护墙(桩)主动区土压力不同,在这种偏压作用下的基坑围护结构方案选型、设计及施工问题就是其中之一。本文结合实际工程,采用有限元分析软件PLAXIS,分析了基坑围护结构在不同偏载作用下的受力与变形规律,并提出了在偏载作用下基坑围护结构选型的相关应对措施,研究成果对工程实践具有一定的指导意义。
Many difficult problems have been encountered in the development and utilization of underground space. Due to the restriction of environmental and planning sites,the earth pressures on the active area of retaining walls（piles） on both sides of the foundation pit are different.Under the foundation pit retaining structure program selection,design and construction issues is one of them. In this paper,combined with the actual project,the finite element analysis software PLAXIS is used to analyze the stress and deformation of the retaining structure of foundation pit under different partial loads,and the relevant countermeasures of the selection of the retaining structure of foundation pit under partial loading Measures,research results have some guiding significance for engineering practice.
