摘要
结合核电建设中测量实际情况,以某核电站边角网实测数据为例,对多种模型下的处理结果进行了比较,指出可以优先选用测边网;强调运用Helmert验后方差估计处理测量数据时,取待定点坐标初值尽可能精确,否则会导致迭代求解失效,得不到最终结果.
Considering the practical conditions about the application of surveying control network during nuclear power plant（NPP） construction,with the calculation result of a real triangulateration data comes from the control network of one NPP being built, the paper gives supports on why trilateration should be selected firstly; it also shows given accurate initial coordinates of the unknown points are important and necessary,otherwise the equations can＇t be iterated continuously and the final result can＇t be obtained either.
