摘要
桩锚支护结构在深基坑支护工程中已得到广泛应用,为使支护方案更加经济合理,本工程在锚头上安装轴力计,监测基坑开挖过程中锚杆拉力的变化,同时结合锚杆验收试验成果、基坑桩顶水平位移监测成果,与理论设计计算结果进行对比、分析,从而进一步优化基坑支护设计方案,为类似工程的基坑支护设计工作提供参考。
Pile-anchor retaining structure obtained the widespread application in the deep foundation pit retaining structure engineering project, In order to cause the retaining plan to be more economical reasonably ,This project installs the axle strength measuring instrument on anchorage, follows the foundation pit to excavate downward, carries on the monitor to the anchor rod pulling force, simultaneously unifies the anchor rod inspection acceptance testing achievement. The head of pile horizontal departure monitor achievement, carries on the contrast and analysis with the theoretical design and computed result, then, deep level development high quality plan, for similar project provides the reference in the deep foundation pit retaining structure plan design.
