高速铁路精密测量控制网复测的分析研究

摘要

铁路轨道结构等级与运输条件密切相关。在铁路运输发展的初期，速度、轴重、密度都处于较低水平，对轨道结构的要求以可靠性为主。随着高铁近年来的迅猛发展，对传统的铁路设计、施工、检测、养护维修提出了新的挑战。在高速铁路建设过程中,建立有效、经济实用的精密测量控制网是保障工程施工、放样及运营维护精度的前提。应用精密工程控制测量和高速铁路轨道技术，以现有的规范和轨道平顺性指标为指导，在分析现有高速铁路轨道控制测量理论的基础上，利用GPS技术和传统精密测量技术对轨道进行复测，对其相应的精度指标进行统计和分析，从而使高铁运行更加安全可靠。

HIGH SPEED RAILWAY PRECISE SURVEYING

CONTROL NETWORK REPETITION ANALYSIS

RESERCH

ABSTRACT

Railway track structure level is closely related to the transportation conditions. In the early stages of the development of railway transportation, speed, axle load, density is low, the requirement of track structure is given priority to with reliability. With the rapid development of high-speed rail in recent years, the traditional railway design, construction, testing, maintenance and repair is putting forward a new challenge. In the process of high-speed railway construction, establish an effective, economical and practical precision measuring control network is the guarantee of project construction, layout, and precision is the premise of the operation and maintenance。Precision engineering control survey technology, and high-speed railway track to the existing specification and orbital comfort index as the instruction, based on the analysis of the existing high-speed railway track control measurement theory, on the basis of using GPS technology and traditional precision measurement technology to retest of orbit, its corresponding precision index statistics and analysis, so that high-speed rail is more safe and reliable operation.
