摘　　要：苏州市轨道交通工程自3号线建设以来,引入了高速铁路CPⅢ测量成套技术,用于替代传统的轨道基标测量。智能型全站仪配合任意设站星状控制网,在大幅度提高城市轨道交通工程控制网相邻点位精度的同时,也带来控制网规模过大、计算效率低下的问题。基于矩阵行、列压缩存储原理,研制苏州市轨道交通工程控制网数据处理程序,以提高大型控制网的平差速度,并将其应用在苏州市轨道交通工程控制网中,对减少内业计算压力,提高内业工作效率,减少搭接区域数量,提高工程控制网整体性有一定帮助。Since the construction of Suzhou rail transit line 3,a complete set of high-speed railway CP III measurement technology has been introduced to replace the traditional track benchmark measurement.The intelligent total station cooperates with any station Star control network,which not only greatly improves the accuracy of adjacent points of the rail transit engineering control network,but also brings the problems of too large scale of the control network and low calculation efficiency.Based on the principle of matrix row and column compression storage,this paper develops the data processing program of Suzhou rail transit engineering control network,improves the adjustment speed of large-scale control network,and applies it to Suzhou rail transit engineering control network,which is helpful to reduce the internal calculation pressure,improve the internal work efficiency,reduce the number of overlapping areas and improve the integrity of engineering control network.
