在基坑施工过程中,由于土方扰动、地下水位下降、荷载增加以及其他一些不确定的因素,引起周围环境的变化,导致支护结构发生变形,如果支护加固不及时,将严重影响周围建筑物和市政设施安全,本文通过对武汉某地深基坑支护结构监测方法及精度分析进行研究,实例验证了深基坑支护结构监测实施的必要性和可行性。
During the construction process of the foundation pit, due to disturbance of earthwork, descending of groundwater level, increase of load and other uncertainties, the surrounding environment will be changed and the supporting structure will be deformed. If the support is not strengthened in a timely manner, it will seriously affect the surrounding buildings This paper studies the monitoring method and precision analysis of the deep foundation pit supporting structure in a certain place in Wuhan, and realizes the necessity and feasibility of monitoring the deep foundation pit supporting structure.
