测量控制改造网灵敏度的优化设计

以改造测量控制网灵敏度优化设计为理论基础,对某一三角网的部分网形进行了改造灵敏度的优化设计。在设计中采用了在原网中加测一部分边长,以降低网形的整体灵敏度来改善原控制网的质量。采用改造控制网灵敏度的优化设计方法,可以获得一种测量工作量最小,经济指标最高的改造方案,并能提高原有测量控制网的精度。

An Optimized Design of the Sensitivity for the Reformed Surveying Control net

Taking the optimal design of sesitivity for the reformed sueveying control net as theoetical basis,the paper presents an optimal design of the reformed sensitivity for a part of net in a triangle net.We improve the quality of oringinal control net by using the reduced integral sensitivity.It will gives the reformed scheme with the minimum surveying operation and maximum economy indexes,and improved accuracy to carry out the optimized design sensitivity for reformed surveying control net.
