探讨三角高程测量代替二等水准测量的方法

Method of the trigonometric leveling replacing the second grade leveling

根据高速铁路工程测量路线极长,沿线地形复杂多变,测量精度要求高的特点,提出了一种三角高程测量代替二等水准测量的方法,对高精度三角高程测量的严密公式及误差进行了分析,研究了TCRP1201全站仪复合对边测量原理、方法及其精度。

Based on the long measuring line of the high speed railway construction, the complicated terrain along the line, the high requirement of the precision, the author puts forward the trigonometric leveling to replace the second grade leveling, analyzes the formula and the error of the high precision trigonometric leveling, studies the composite remote distance measurement principle, the method and the precision of TCRP1201 total station.
