摘　　要：客运专线平顺性要求非常高,轨道测量精度要达到毫米级。其测量方法、测量精度与传统的铁路工程测量完全不同,要实现客运专线铁路轨道的高平顺性,除了对线下工程和轨道工程的设计施工等有特殊的要求外,必须建立一套与之相适应的精密工程测量体系(以下简称精测网)。文中从精测网的布设及技术要求,系统介绍了精测网的技术设计,并对其测量成果进行了精度分析,对客运专线铁路精密工程测量控制网的建立有实际指导意义。The smooth requirements of the passenger railway line is very high that the rail measurement accuracy is to be achieved millimeter.The measurement method and the measurement accuracy are completely different comparing with the traditional railway engineering measurements.It must establish a precision engineering measurement system (Requirements the fine observation network) beside the special requirements of designing and constructing the underline engineering and track engineering to achieve the smooth requirements of the passenger railway line.In the paper,the author introduces the technical design of the precise surveying network and analyzes the measurement results precision.It is practical guiding significance to the technical design of the precision measurement control nets on passenger line.
