摘要
文章以广西贵港西江航运建设二期工程船闸安全监测项目为例,介绍了三边长后方交会法的基本原理,推导出三边长后方交会法的坐标计算、平差公式等,分析了其误差来源和控制措施,论证了三边长后方交会在精密测量工程中的可行性与优越性。
With the ship-lock safety monitoring project in Guigang Xijiang Navigation Con- struction Phase II engineering as the example,the article described the basic principles of td-side resection method, deduced the coordinate calculation and adjustment formulas of tri- side resection method, analyzed the sources of its errors and the control measures, and demonstrated the feasibility and superiority of tri-side resection method in precision meas- urement engineering.
