GPS配合全站仪在机场边坡变形监测中的应用

GPS and Total Station Using in the Airports Slope Deformation Monitoring

针对某高填方机场边坡变形监测问题,为使变形监测精度达到《建筑变形测量规范》二级精度要求,提出了GPS方法进行控制测量,控制网分级布设,精密解算与常规解算相结合的解算方式,变形监测采用基于单台全站仪的自由设站方法,从而形成控制测量与变形监测优势互补,同时达到了经济、高效,为今后解决类似工程问题提供了成功经验。

This paper addresses the problem of some thick filling airports slope deformation monitoring.To make accuracy meet the second class accuracy request of Code for deformation measurement of building and structure,it puts forward a control measure proposal of GPS method,rating the control net,solution way adoption precise solution calculate with normal regulations the solution combine together on the whole,and a deformation monitoring proposal of using a single total station to establish station freely.To complete the engineering,these two methods are producing each other＇s advantages,economical and efficient.This engineering provided successful experience for after project.
