文章介绍了跨海高程控制测量的几种主要方法，结合港珠澳大桥岛隧工程控制网以及海中测量平台实际情况，采用测距三角高程法进行跨海高程控制测量。为满足国家二等水准测量规范要求，在天宝TSC3手簿中安装软件与徕卡TS30全站仪连接，提高测量数据精度。经实测数据分析，该软件的使用解决了测距三角高程测量中数据离散性大，数据筛选困难等问题，在多项精度指标上达到了国家二等水准测量规范要求。

Several main methods of sea-crossing elevation control survey were introduced in this paper, and combining with actual situation of the control network and the measuring platform in the Hongkong-Zhuhai-Macao Bridge island & tunnel project, we adopted the range trigonometric leveling method to carry the sea-crossing elevation control survey. To meet the requirements of national second-class leveling, we installed software in Trimble TSC3 hand book and connected with Leica TS30 total-station to improve the accuracy of measurement data. By the measured data analysis, the software used to solve the large discreteness and difficult screening of data during range trigonometric leveling, and achieves the national second-class leveling requirements in a number of precision indexes.
