高速铁路工程测量体系的精度控制与分析——以国内某条高速铁路的某测段工程为例

PRECISION CONTROL AND ANALYSIS OF THE MEASUREMENT SYSTEM OF HIGH SPEED RAILWAY ENGINEERING——WITH A SEGMENT OF SURVEY ENGINEERING OF A HIGH SPEED RAILWAY AT HOME AS EXAMPLE

近些年来,随着国民经济建设的不断发展,高铁建设事业也得到了长足地发展。而铁路轨道精密控制测量技术在现代铁路建设中起到了重要作用,尤其对轨道施工控制精度、列车安全运营有着直接的影响。所以在高速铁路施工前,要对铁路轨道精密工程测量技术体系进行深入细致的研究和分析,运用精密的控制测量技术和方法来控制轨道测量的精度,从而提高铁路轨道的施工质量和安全运营。本文以国内某条高速铁路某测段的CPⅢ平面及高程控制测量技术为例,对轨道控制测量精度进行分析和研究,为此段高速铁路轨道的安全施工提供精密控制测量成果。

In recent years,with the continuous development of national economic construction,a rapid progress has been made in the high speed railway sector.Railway track fine control surveying technique played a great role in the construction,especially having direct effect on the track work control precision and safe running of the trains.So,before construction of a high speed railway,an in-depth and careful research and analysis should be made on the track precision engineering surveying technique system,and fine control surveying technique and method should be applied to track precision control,thus improving the construction quality of track and then safe operation.This paper,with CPIII plane and height control surveying technique application in a segment of a high speed railway at home as example,analyzed and studied the precision of track control surveying for providing fine control surveying results for safe construction of the segment.
