在滑坡堆积体区域内开挖基坑的工程经验很少,不仅需要解决基坑与滑坡堆积体的稳定性问题,同时也需要有效地控制挖土应力释放所引起的滑坡体变形问题,以达到保护滑坡体上建构筑物之目的。本文通过具体工程案例探讨了滑坡堆积体地区深基坑开挖的变形控制设计方法。选择典型剖面建立有限元模型,对基坑开挖及滑坡体加固施工过程再现,分析研究加固对变形控制的效果。监测结果表明,本工程的加固措施以及数值模拟成果都较为可靠,可为类似工程提供借鉴。
It is not only necessary to solve the problem of stability of foundation pit and landslide stack but also to effectively control the deformation of landslide caused by excavation stress release in order to reach the Protection of landslide body building structures purposes. In this paper, the deformation control design method of deep foundation pit excavation in landslide accumulation area is discussed through concrete engineering cases. Select the typical section to establish finite element model, excavation of the foundation pit and landslide reinforcement construction process reconstruction, analysis and reinforcement effect on the deformation control. The monitoring results show that the reinforcement measures and numerical simulation results of this project are more reliable and can provide reference for similar projects.
