地铁保护区自动化监测精度分析

Automatic Monitoring Accuracy Analysis of Metro Protection Area

论述了地铁保护区自动化监测的原理和方法。结合某地铁保护区自动化监测实例,介绍了运营期地铁隧道结构多方位、实时化的信息获取技术,并将自动化静力水准测控系统获取的沉降数据与自动化全站仪测控系统获取的水平位移数据结合人工监测数据进行对比。结果表明,自动化静力水准测控系统获得的沉降数据与自动化全站仪测控系统获得的数据均有较高精度,满足地铁保护区自动化监测的要求,具有良好应用和推广价值。

The principle and method of automatic monitoring for metro protection area are discussed.Combined with the example of automatic monitoring of metro protection area,the multi direction and real-time information acquisition technology of subway tunnel structure during operation is introduced,and automatic static level measurement and control system to obtain the settlement data and automatic total station measuring and controlling system to obtain the horizontal displacement data acquisition combined with artificial monitoring data are analyzed contrast.The results show that,automatic level measurement and control system to obtain the settlement data and automatic total station measuring and controlling system to obtain the horizontal displacement data has high precision,which can meet the subway protective area automatic monitoring requirements and has good application and popularization value.
