城市及工矿区三边控制网模拟试验及其分析

Simulation experiment and its analysis of urban and mine trilateration control network

本文以三边网和三角网的比较讨论有关城市与工矿平面控制网的技术规定。对于三边网也可按相对方位的最弱边来最终评定其精度,即每一锁(网)从起始方位边到最弱边不超过10个三角形。

This paper discusses the specifications of horizontal control network on the basis of the comparison between trilateration and triangulation in urban and mining areas. The precision of trilateration network couId be finally evaluated by the weakest side of azimuth, i.e.for every chain (or net), from the original side to the weakest side of azimuth should not exceed 10 triangles.
