城市地铁车站深基坑施工监测方案设计研究

以北京地铁奥运支线森林公园站南基坑工程为依托,根据深基坑工程施工监测的基本方法和基本原理,结合该深基坑工程的开挖围护方案对其进行了包括坡顶竖向及水平位移、围护桩桩身内力及桩体变形、钢支撑轴力、地下水位等内容的监测系统设计,给出了监测信息的反馈程序及监测数据的分析、预测方法.

Research on Monitoring Scheme of Deep Foundation Pits in Urban Metro Stations

Based on the south deep foundation pit of Forest Park in the branch of Beijing Olympic Games Subway , the monitoring scheme is designed according to the retaining scheme of foundation pit and the monitoring fundamental methods and principles. The scheme includes vertical displacement and horizontal displacement of the slope top,endogenous force and lateral deformation of retaining piles, axial force of steel supports and underground water level. Finally, the monitoring feedback process and the data analytical method and predictive method are given in this paper.
