基坑侧壁位移及应力变化规律的探讨

摘要

In the construction process of foundation pit engineering, there is a close relationship between the deep horizontal displacement and the anchor stress of the foundation pit enclosure. In this paper, the displacement and stress change of the side wall in foundation pit are systematically summarized. The results show that the deep horizontal displacement is closely related to the stress of the anchor cable, and the change of stress of the anchor cable and displacement value influence each other. So the quality and safety management of foundation pit should combine with the the two data in monitoring.%在基坑工程实施的过程中,基坑围护体侧向的深层水平位移和锚固体应力之间往往存在着密切的联系.文章对该基坑施工过程中基坑侧壁出现的位移及应力的变化进行了系统的总结,结果认为:深层水平位移与锚索应力有着十分密切的联系,锚索应力值的变化往往与位移值相互影响,因此工程中可以结合监测时的两项数据对基坑的质量安全进行管理.
