摘要
铁路客运专线复测工作是精密工程控制测量技术逐渐发展完善的过程,其应用技术可以给铁路项目的设计、施工、运营与维护提供参考。研究了京沈铁路北京段的精密工程测量平面网与高程网布设的技术体系,结合往期数据与已有资料,利用基础平面控制网(CPⅠ)与线路平面控制网(CPⅡ)分析对比了漏斗沉降区域部分段路的控制测量成果,其平面精度与高程精度都受到了一定影响。数据结果真实有效,测量技术方案以及研究结果对于同类铁路精密工程控制测量技术有重要参考意义。
The retest of railway passenger dedicated line is a process in which precision engineering control surveying technology is gradually developed and perfected.Its application technology can provide reference for the design,construction,operation and maintenance of similar railway projects.The research discusses the technology system of the precision engineering survey plane network and elevation network of the Beijing section of the Beijing-Shenzhen Railway.Using CPⅠand CPⅡ,combined with previous data and existing data,some sections of the funnel settlement area are analysed and compared.The elevation accuracy has been affected to some extent.The data results are real and effective,and the measurement technology plan and research results have important reference significance for the similar railway precision engineering control measurement technology.
