摘　　要：跨海高程控制测量是现代大型桥梁工程测量的难点,结合杭州湾跨海大桥施工高程测量控制网的建立,以ATR技术为硬件基础,介绍ATR三角高程测量的具体实施方法。经实测数据分析,采用ATR三角高程测量,在多项精度指标上均达到了国家三等水准测量的要求。The control survey of sea-crossing leveling is a difficult point in the survey of modern major bridge engineering. In this paper, in the light of establishing of the control network for the construction leveling of Hangzhou Bay Sea Crossing Bridge and on the basis of application of ATR technique, the specific methods for implementation of the ATR trigonometric leveling are presented. The analysis of the actual measurement data obtained from the leveling demonstrates that a good many precision indexes of the control survey using the ATR trigonometric leveling can satisfy the requirements of Grade 3 Leveling of the State.
