【摘要】 GZCORS具有快速、准确、全方位、全天候定位的特点。本文以广州亚运城地下综合管线竣工验收工程为例,阐述了采用GZCORS代替等级控制导线进行控制测量的作业模式。该模式有效的解决了管线量大与控制点少二者之间的矛盾,在快速城市化背景下的城市地下管线探测中有着广阔的应用前景。更多还原

【Abstract】 GZCORS has a fast, accurate, comprehensive, all-weather positioning feature. In this paper, completion and accep- tance of the Guangzhou Asian Games City underground pipeline as an example, it describes the mode of operation using GZCORS for control measurement instead of level control wire. The mode effectively solves the contradictions between a large number of pipelines and few control point. It has broad application prospects in the urban underground pipeline detection in context of rapid urbanization.更多还原
