摘　　要：传统三角高程测量进行陆地到岛屿间的高程传递精度较低。本文分析了跨海水准测量误差来源,阐述了中间设站法三角高程测量原理,在此基础上,基于Leica TM30测量机器人,利用改进后中间设站三角高程测量的方法,实现从陆地到岛屿的高程传递。以福建黄干岛、乌屿两处岛屿为例,应用跨海水准联测,对测量成果精度进行分析。结果表明,该方法测量成果能够达到国家二等水准测量精度要求,减轻了劳动强度,提升了工作效率,在同类工程中具有一定的借鉴意义。The accuracy of the tradictional trigonometric leveling is low for the elevation transmission from land to island.This paper analyzes the source of cross-sea leveling error,expounds the principle of trigonometric leveling of the intermediate station method.On this basis,the elevation transmission from land to island is realized by using the improved metermediate station trigonometric leveing based on leica TM30 measuring robot.It takes the two islands of Huanggan Island and Wu Yu in Fujian Province as an example,and applies cross-sea water quasi-combination to analyze the accuracy of the measurements.The results show that the measurements of this method can meet the requirements of second-order national measurement accuracy,reduce workingloads,improve work efficiency,so it has some useful reference significance in similar projects.
