基于徕卡TS30全站仪的桥墩平面位移监测应用研究

Research on the Application of Leica TS30 Total Station in the Plane Displacement Monitoring of Bridge Piers

以中石化投建的日照—濮阳—洛阳原油管道下穿郑焦城际高铁项目为例,阐述了在邻近高铁桥墩基坑开挖施工中,利用徕卡TS30高精度全站仪进行桥墩平面位移监测的应用。测量施工方案为现场自由架站,以4个已知控制点进行后方交会设站定向,且仪器架站距监测点的距离约为60 m,然后采用按监测点编号顺序观测的方式对桥墩进行监测测量。按照该方法,利用徕卡TS30高精度全站仪对相关高铁桥墩进行观测,能快速、准确监测高铁桥墩平面位移变化的数据信息。

Taking the project of the Rizhao-Puyang-Luoyang crude oil pipeline under the Zhengjiao intercity high-speed railway built by Sinopec for example, we described the application of the Leica TS30 high-precision total station in the plane displacement monitoring of bridge piers, which in the excavation of the foundation pit near the high-speed railway bridge pier. The survey construction scheme is a free-standing station on site, which based on the principle that the rear intersection of four known control points is to be oriented, and the distance between the instrument stand and the monitoring point is about 60 meters. Then, the piers are monitored and measured according to the serial observation of monitoring points. The Leica TS30 high-precision total station is used to monitor the relevant highspeed railway bridge piers, which can quickly and accurately monitor the data information of the plane displacement changes of high-speed railway bridge piers.
