摘要
介绍了基于固定式测斜仪的地铁基坑墙体深层水平位移自动化监测系统组成,详细阐述了系统应用于常州轨道交通2号线一期工程某车站主体基坑监测实施情况。在自动化监测点位旁布设人工监测点位,并比较两种方法的结果。结果表明,该系统实现了监测数据的自动采集、传输及处理,实时提供监测成果并绘制变形曲线。并且自动化监测成果精度可满足施工监测的需求,成果可真实反映基坑墙体在水平方向上的变形情况。
The paper introduces the composition of automatic monitoring system for deep horizontal displacement of subway foundation pit wall based on fixed inclinometer. Elaborating the application of the system to the monitoring and implementation of the main foundation pit in the phase I project of Changzhou rail transit line 2 in detail. Setting up an artificial monitoring point by the side of the automatic monitoring point and comparing the results of the two methods. The results show that the system realizes automatic collection, transmission and processing of monitoring data, provides monitoring results in real time and draws deformation curve. The accuracy of automatic monitoring results can meet the needs of construction monitoring. The results can truly reflect the deformation of the foundation pit wall in the horizontal direction.
