CP Ⅲ技术在变形监测中的应用

摘要

CPⅢ控制网是直接控制无碴轨道施工的最后一级平面、高程控制网，已经在高速铁路建设中大量采用，其数据采集和数据处理技术已日趋成熟。文中结合重庆市某桥墩变形监测项目，介绍将CPⅢ技术应用于变形监测工程的操作流程。监测结果表明，CPⅢ后方交会测量精度达毫米级，能够满足大部分变形监测工程的精度要求。%As the final level flat and vertical control network of Non‐ballast Track ,CPIII control network has been used in high‐speed railway construction ,of which the data acquisition and data processing technology have matured .It presents the CPIII operation flow deformation monitoring project ,combined with a pier deformation monitoring project in Chongqing .Monitoring results show that CPIII resection measurement has reached an accuracy of millimeter level ,w hich can meet the requirements of most deformation monitoring projects .
