| 摘 要： | 三角高程测量方法因其便捷性成为跨河(海)高程传递中应用较广泛的技术,按照《国家一、二等水准测量规范》规定,三角高程测量法的跨河(海)距离最大为3 500 m。本文基于三角高程测量的基本原理,在现有跨河(海)三角高程传递方法的基础上,提出了优化改进的方法,以实现更长距离(10 km以上)的高精度(国家二等水准精度)的跨河(海)高程传递。

| Abstract: | Because of its convenience,the triangulation elevation measurement method has become a widely used technology in the crossing river(sea)elevation transmission.According to The National Standards for the First and Second Class Level Measurement,the triangulation elevation measurement method is limited to the crossing(sea)distance of 3500 m.In this paper,based on the basic principle of triangulation height measurement,and on the basis of the existing methods of triangulation height transfer across river(sea),an optimized and improved method is put forward to realize the high-precision(national second-class leveling precision)tri-angulation height transfer across river(sea)with longer distance(more than 10 km). |

| Keywords: | trigonometric leveling long-distance crossing river(sea) height transmission improvement |
