由于基坑开挖过程中坑内土体被挖除,挡墙向坑内移动,墙后土体受扰动产生竖向不均匀沉降。此沉降将打破建筑物原有的受力平衡体系,使建筑物产生附加力及变形,严重时将导致建筑物的破坏。总结了深基坑周边沉降的影响因素,因此基础上提出了控制沉降的方法。确保项目最经济、最有效的完成。 Due to the excavated soil in the excavation process, the retaining wall moves to the inside of the pit, and the disturbed soil behind the wall produces vertical and non-uniform settlement. This settlement will break the original stress balance system of the building, causing additional force and deformation of the building, which will lead to the destruction of the building in serious cases. The influencing factors of settlement around the deep foundation pit are summarized. Therefore, a method of controlling the settlement is proposed. Make sure the project is the most economical and efficient to accomplish.
