高精度控制网优化程序设计及实现

Design and Implementation of High Precision Control Network Optimization Program

控制网的设计及成果准确性是工程建设的基础。对于大中型工程而言,无论施工控制网、变形监测网还是安装控制网等,其优化设计都是很有必要的。从控制网的质量准则出发,设计一套完整的计算程序。通过案例分析,控制网优化前、后成果与COSA软件进行对比,无论是点位精度还是最弱边精度,两者是一致的。同时,该计算程序较COSA增加了可靠性指标,优化结果表达更全面。该程序在使用上,如参数调整更方便,人为干预更少,完全无需人工辅助计算,更具优越性,尤其是控制点位增减、方向及边长删减更方便。与COSA的对比,说明本程序计算结果的准确性和可靠性。

The design of control network and the accuracy of results are the basis of engineering construction.For large and medium-sized projects,it is necessary to optimize the design of construction control network,deformation monitoring network and installation control network.Based on the quality criterion of control network,this paper designs a complete set of calculation program.Through the case analysis,the results before and after the optimization of control network are compared with COSA software,and both of them are consistent,no matter the point accuracy or the weakest edge accuracy;at the same time,the reliability index is added in this program compared with COSA,and the optimization results are more comprehensive.The program in this paper has more advantages in use,such as more convenient parameter adjustment,less human intervention,no need of manual calculation,especially more convenience for the increase and decrease of control points,direction and side length.According to the comparison with COSA,the accuracy and reliability of the calculation results of this program are explained.
