摘　　要：普通铁路的低精度控制网已经无法满足新时期铁路运营维护的需要,采用轨道控制网(CPⅢ)控制测量体系对重建普通铁路控制网具有重要意义。为研究CPⅢ测量技术和方法,本文以某铁路控制网重建项目为例,介绍铁路控制网布设要求,详细介绍CPⅢ加密测量、平面测量、高程测量的技术方法。结果表明,本次建网测量各项控制指标均符合规范要求,研究内容可为相关工程应用提供参考。The low precision control network of ordinary railways can not meet the needs of railway operations and maintenance in the new period.It is of great significance to reconstruct the control network of ordinary railway by using the control and measurement system of foundation pile control network(CPⅢ).In order to study the CPⅢ measurement technology and method,this paper takes a railway reconstruction project as an example,introduces the railway control network layout requirements,and introduces the technical methods of CPⅢ encryption survey,plane survey and elevation survey in detail.The results show that the control indexes of the network construction survey meet the requirements of the code,and the research content can provide reference for related engineering applications.
