摘 要: 针对传统普速铁路轨道控制网平面网的建网、施测和数据处理方法,参照高速铁路CPⅢ自由测站边角交会网,提出一种普速铁路新型轨道控制网平面网的建网和施测方法,并对这种新型网和传统网的精度进行仿真计算和精度分析。在一段既有铁路上布设这种新型网,对新型网进行观测和数据处理实验。研究结果表明这种新型的轨道控制网较之传统的导线网具有多方面的优势,可以作为一种新型轨道控制网在普速铁路轨道测量中得到应用。

Abstract:Firstly, the paper introduces establishment,measurement and data processing of horizontal track control network for ordinary-speed railway. Then, it proposes a new method for plane network’s establishment and measurement of ordinary-speed railway track control network based on the high-speed railway CPⅢ free station side-angle intersection network. Simulation calculation and accuracy analysis were performed for the new network and traditional network. Measurement and data processing were done for the new network which was established on an existing railway line.The results show that the new track control network has much advantages than traditional network,and it can be used as a new kind of track control network in ordinary-speed railway track measurement.

 

Key words: ordinary-speed railway;track control network;precision estimation;mean square error of a point;free station side-angle intersection network
