高速铁路无砟轨道板抬升修复施工测量技术与应用

Construction Measurement Technology and Application of Ballastless Track Slab Uplift and Repair in High-speed Railway

因自然因素导致新建或既有高速铁路沉降量过大的问题,需对无砟轨道板进行抬升修复达到设计标高。该文主要介绍了测量技术在高速铁路抬升修复施工中的应用,通过某实际项目案例,从CPⅢ复测、轨顶高程测量、高程放样测量、动态实时监测等方面进行深入分析研究,总结出测量技术在无砟轨道板抬升修复中的施工工艺和流程,对后期类似工程具有一定借鉴意义。

Due to natural factors,the settlement of new or existing high-speed railway is too large,so it is neccessary to lift and repair the ballastless track slab to reach the design elevation.In this paper,the application of measurement technology in the uplift and repair construction of high-speed railway is mainly introduced.Through a practical project case,it conducts in-depth analysis and research from CP II remeasurement,rail top elevation measurement,elevation lofting measurement,dynamic real-time monitoring,etc.,and summarizes the construction technology and process of surveying technology in the uplift and repair of ballastless track slab to provide some reference for the similar construction in later period.
