深港西部通道平面及高程控制网联合测量

横过后海湾的深港西部通道，是一条连接香港和深圳两地的策略性跨境道路大桥，由香港特别行政区政府和深圳市人民政府共同投资兴建。兴建大桥用的平面及高程控制网的联合测量由香港路政署和深圳市深港西部通道工程筹建办公室联合策划和完成。论文讲述两地的坐标和高程系统转换关系，汇报了建立大桥专用的独立坐标系统及连接两地高程系统的工作和成果。

Hong Kong -Shenzhen Western Corridor Joint Control Survey for the Horizontal and Vertical Control Networks

The Hong Kong-Shenzhen Western Corridor (HKSWC) stretching across Deep Bay will be a strategic cross-boundary link between the Hong Kong Special Administrative Region and the City of Shenzhen in the Mainland of China. The joint control survey was conducted by the Highways Department in Hong Kong and the Shenzhen-Hong Kong Western Corridor Project Office in Shenzhen. The paper will give an account of the relationship between different coordinate systems and height datums being used in Hong Kong and Shenzhen. It also describes the establishment of a project-oriented independent horizontal survey control network and the connection of the height datums of the two places by survey parties on both sides of the project.
