海南东环铁路美兰机场地下车站变形监测技术研究

Research on Deformation Monitoring of Meilan Airport Underground Station on Hainan Eastern-ring Railway

高速铁路建设和后续运营维护,对构筑物、轨道等变形有严格的限制,因此,变形监测问题已成为高速铁路设计所考虑的一个重要因素。文章以海南东环铁路美兰机场地下车站变形监测为研究背景,探讨了车站变形监测基准点、工作基点以及监测点的布设方法、数据采集精度要求以及监测数据的处理和分析方法。结果表明:基于美兰机场车站变形监测所建立起来的变形监测基准点、工作基点以及变形监测点具有合理、高效、实用且能准确反映车站实际是否变形情况的特点,因此,其整个监测过程取得了较好的效果,达到监测目的。

Deformation monitoring of high speed railway has been proved to be a key factor in design as there is a strict restriction on deformation of the structures and rails of high speed railway in both periods of construction and operation maintenance.Taking the deformation monitoring of Meilan Airport Underground Station on Hainan Eastern-ring Railway as the study case,the paper discusses the arrangement of reference point,working point and monitoring point for station deformation,requirement for data collection and processing and analysis of monitored data.The study result indicates that the reference point,working point and monitoring point for station deformation established in deformation monitoring net has the characteristics of rationality,efficiency and practicality and has also correctly reflected the deformation of the station,therefore,preferable effect has been produced and monitoring objective has been realized in the monitoring process.
