摘要
为保证既有线胶济客专线上施工及运营维护管理等各阶段工作精度需求,对原精密测量控制网进行复测,将既有单侧CPIII导线网改造为线路双侧控制网,采用在线路两侧安装独特设计的抱箍件形式,实现高效、低成本恢复线上CPIII网,弥补了既有CPIII导线网横向偏差的劣势。本文阐述了项目的技术依据、外业观测要求、内业数据处理方法,以及得到精测网复测与原测成果对比分析结论,科学合理地提供出控制网成果,为线路养护提供了可靠基准。
In order to ensure the accuracy requirements of the construction,operation and maintenance management of the existing Jiaoji passenger dedicated line,the original precise survey control network was retested.The existing one-sided CPIII traverse network was transformed into the bilateral control network of the line.The unique hoop shape was installed on both sides of the line to realize the efficient and low-cost restoration of the CPIII network on the line and make up for the lateral deviation of the existing CPIII traverse network The disadvantages of.This paper describes the technical basis of the project,field observation requirements,data processing methods in the field,and obtains the conclusion of comparative analysis between the re survey and the original survey results of the precise survey network,so as to provide scientific and reasonable control network results and provide reliable reference for line maintenance.
