Abstract

Based on a detailed examination on existing survey system in the project area and aimed at the characteristics of the Middle Route of South-to-North Water Diversion Project,a survey datum with multiple levels,,high precision and large range was constructed to meet the project construction requirements.It mainly consists of B-level GPS mainstay networks,C-level GPS networks,second order leveling network for channel route,and construction control network for buildings.It found a way out of incompatibility in time and space between network pointsand provided useful experiences for other similar long-distance projects in terms of survey datum construction method,control grade,technical specifications and data processing.

南水北调中线工程测量基准建设研究

在详细审查项目区现有测量系统的基础上，针对南水北调中线工程的特点，构建了满足工程建设要求的多层次、高精度、大范围的测量基准。它主要由b级GPS支柱网、c级GPS网、通道路由二级水准网和建筑物施工控制网组成。为解决网点间时空不相容的问题，在测量基准面施工方法、控制等级、技术规范、数据处理等方面为其他类似长距离工程提供了有益的经验。
