摘　　要：在简要阐述导线网、测角三角网、三边网、特殊三角形图形结构近似坐标推算的基础上,论述复杂网型平面控制网近似坐标推算,重点论述了复杂网型结构的约束条件、近似坐标推算的顺序等内容,并编写对应的平差程序,经过多个复杂网型的实践检验,结果完全正确,验证了方法的可靠性,解决了复杂网型的近似坐标推算问题。This study described the calculation of the approximate coordinates of the wire mesh,the angle of the triangle net,the three sides of the triangle,and the special triangle graphic structure. According to previous description,this paper further discussed the approximate coordinates of the complex network and emphasized the constraint of complex network and order of approximate coordinate calculation. Corresponding adjustment programs were written afterwards. The calculated results were verified to be totally correct by many applications of complex network,which suggested that the proposed method in this study was reasonable and can successfully solve the approximate coordinate calculation of complex network.
