客运专线无砟轨道桥梁垂直位移观测技术

桥梁工程在客运专线结构中占相当大的比例,是变形观测及评估的重要组成部分。桥梁垂直位移观测测点多,线路长,精度要求高,在国内尚无成熟经验。结合郑西客专变形观测实践,从监测网的建立、仪器使用、观测路线选择等多个方面阐述了垂直位移观测技术,对客运专线无砟轨道桥梁垂直位移观测有一定的借鉴和指导价值。

Observation Technology of Bridge Vertical Displacement in Passenger Dedicated Line Balastless Tracks

Bridge works is an important component of deformation observation and evaluation which accounts for a considerable proportion in passenger dedicated line structure.There is no relevant domestic mature experience because of a large number of observation points,long lines and high accuracy for bridge vertical displacements.Based on deformation observation practice in Zhengzhou-Xi'an Passenger Dedicated Line,this article expounds the vertical displacement observation technique from many aspects,such as establi...
