近年来,随着铁路列车不断提速,许多路基工程出现不同程度的病害,给运营带来较大安全隐患,已越来越引起铁道部的重视,在设计及施工方面提出更高的要求,路基变形观测工作未通过评估验收,一律不予进行道碴、轨道施工,故路基变形观测工作也被作为一道必不可少的工序,贯穿整个施工过程。 In recent years, with the continuous acceleration of railway trains, many subgrade projects have varying degrees of disease and bring great potential safety hazards to operations, which have drawn increasing attention from the Ministry of Railways and put forward higher requirements in terms of design and construction. Subgrade Deformation observation did not pass the assessment and acceptance, will not be carried ballast, track construction, so the deformation of subgrade observation work is also an essential process, throughout the construction process.
