以西安地铁某车站深基坑工程为依托,根据深基坑工程施工监测的基本方法和基本原理,给出了深基坑围护和变形的监测方案,研究了深基坑变形规律,确保了地铁车站的安全施工。重点分析了围护桩体的水平变形和钢支撑轴力的变化规律。研究结果可对类似工程的信息化施工提供参考。
Based on the deep foundation pit project of a station in Xi’an Metro, according to the basic method and basic principle of deep foundation pit construction monitoring, the monitoring plan of deep foundation pit enclosure and deformation is given. The deformation law of deep foundation pit is studied to ensure Metro station safety construction. The variation regularity of horizontal deformation of retaining wall and axial force of steel support are analyzed emphatically. The results of the research can provide reference for the information-based construction of similar projects.
