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。
According to the characteristics of high-speed railway engineering such as extremely long measuring route, complex and varied topography along the line and high measuring precision, a method of triangulation leveling instead of second-level leveling is proposed. The rigorous formulas and error of high-precision triangle leveling Analyzed and studied the principle, method and precision of the TCRP1201 total station compound edge-to-edge measurement.
