高铁路基变形监测的布设方案和技术应用研究

Research on Layout and Technical Application of Deformation Monitoring for High-speed Railway Roadbed

基于高铁路基变形的因素分析,论述变形观测在高铁运营过程中的重要性和技术要求,结合宁波江北张家畈河二期综合整治工程的实施,在河道开挖过程中对萧甬铁路路基沿线进行变形观测,论述高铁路基变形监测的技术要点和技术方法,对类似工程有一定的借鉴意义。

Based on the analysis of the factors of the deformation of the high speed railway subgrade, the importance and the technical requirements of the deformation observation in the process of the high speed rail operation are discussed. Then, based on the implementation of the two period comprehensive renovation project in Zhangjia River, Jiangbei, Ningbo, the deformation observation on the roadside of the xiaosyong railway is introduced.High speed railway roadbed deformation monitoring technology points and technical methods, has certain reference significance.
