津秦客运专线桥涵沉降观测技术

沉降观测是高速铁路施工测量的一项重要内容,其实现需要有相应的测量技术作保证。以津秦客运专线桥涵沉降观测为背景,系统介绍了实施沉降观测所采用的一些关键技术,如观测标设置、沉降观测、观测周期及观测过程中应注意的事项等,为以后高铁沉降观测提供了一些有益的经验。

Settlement Observation Technology for High-speed Railway Bridges and Culverts

Settlement observation is an important content and key in high-speed railway construction measurement, the re- alization of which requires the guarantee of relevant measuring techniques. Using the settlement observation of bridges and culverts in Jin-Qin PDL as a background, this paper systematically introduces some key techniques in settlement observa- tion, such as setup of observation points, settlement observation, observation period and attentions in the observation process, providing useful experience for the future settlement observation in high-speed railways.
