目前国家和相关部门加强了对深基坑变形监测的重视,深基坑变形监测的监测原理和监测方法得到了一定的研究和发展。本文以北京某深基坑工程为研究对象,根据基坑周边环境、工程地质条件及水文地质条件,依据相关规范并结合基坑特点制定了基坑变形监测方案,描述了基坑监测的各个监测项目的内容以及各监测点的点位分布情况,对基坑土钉墙坡顶水平位移、土钉墙坡顶竖向位移、护坡桩坡顶水平位移、护坡桩坡顶竖向位移、深层水平位移、土钉及锚杆拉力、地下水位的监测方法及监测结果进行了分析。结果表明,本基坑监测项目和方法适当,能够真实准确地反映基坑的变形情况,基坑变形存在一定的规律性,其监测方法和变形规律,对其他深基坑变形监测的实施和研究,具有一定的参考价值和意义。
At present, the state and relevant departments have stepped up the emphasis on deep foundation pit deformation monitoring. The monitoring principle and monitoring method of deep foundation pit deformation monitoring have been studied and developed. In this paper, a deep foundation pit project in Beijing is taken as the research object. According to the surrounding environment of foundation pit, engineering geological conditions and hydrogeological conditions, a foundation pit deformation monitoring program is formulated according to the relevant rules and the characteristics of foundation pit. The monitoring of each pit The contents of the project and the distribution of points at each monitoring point, the horizontal displacement of soil nailing wall at the foundation pit, the vertical displacement of top of soil nailing wall, the horizontal displacement of top of slope, the vertical displacement of top of slope, Displacement, soil nails and anchor tension, groundwater level monitoring methods and monitoring results were analyzed. The results show that the project and method of foundation pit monitoring are appropriate, which can truly and accurately reflect the deformation of the foundation pit. There is a certain regularity of the deformation of foundation pit, its monitoring methods and deformation rules, and the implementation and research of other deep foundation pit deformation monitoring , Has a certain reference value and significance.
