佛山市二等水准网的优化设计

A Optimal Design of the Second Grade Level Net in Fuo shan

本文介绍了佛山市二等水准网项目的优化设计,重点阐述了根据间接平差原理对不同的布网方案,利用EXCEL的矩阵计算功能实现精度评估的方法,评选出一套从网形、点位密度、精度、可靠性等方面都符合国家规范和佛山特点的方案,以供参考。

The paper introduces the optimal design of the second grade level net in Fuoshan,expounds the evaluating method on accuracy for different net pattern based on the principle of indirect balancing and the computing function of the EXCEL matrix,and selects a pattern which meets the needs of national norm for net form,the density of point,accuracy and reliability.
