CORS在地下金属管线定位测量中的应用

Application of CORS in positioning survey of underground metal pipeline

城市建设对地下金属管线的测量精度要求越来越高,CORS系统可以提高测量项目的精准度。因此提出CORS在地下金属管线定位测量中的应用这一课题。实现CORS在地下金属管线定位测量中的应用,首先要布置测量控制网络进行地下金属管线定位测量,然后采集管线测量数据信息,最后利用CORS系统实现定位数据处理与储存。设计对比实验,使用传统方法和融入CORS的测量方式进行地下金属管线定位仿真实验,实验结果证明使用融入CORS的测量方式得出测量结果误差更小。

Urban construction requires higher and higher accuracy of underground metal pipeline measurement.CORS system can improve the accuracy of measurement project.Therefore,the application of CORS in underground metal pipeline positioning measurement is proposed.In order to realize the application of CORS in underground metal pipeline positioning measurement,the first step is to arrange the measurement control network for underground metal pipeline positioning measurement,then collect the pipeline measurement data information,and finally use CORS system to realize positioning data processing and storage.A comparative experiment is designed.The traditional method and the measurement method integrated with CORS are used for the simulation experiment of underground metal pipeline positioning.The experimental results show that the measurement error of the measurement method integrated with CORS is smaller.
