保持客运专线无碴轨道持续稳定的高平顺性,是高速运行的列车对无碴轨道基础工程最基本的技术要求。以无碴轨道基础工程(路基、桥梁和隧道)沉降或变形控制为切入点,从施工的角度分析客运专线无碴轨道基础工程技术特点,提出关键的施工技术对策,并对需要进一步研究和解决的施工技术问题进行探讨。
Maintaining sustained and stable high ridership of ballastless track on passenger dedicated lines is the most basic technical requirement for ballastless track foundation engineering for high-speed trains. Taking the settlement or deformation control of ballastless track foundation engineering (subgrade, bridge and tunnel) as the starting point, this paper analyzes the technical features of ballastless track foundation engineering of passenger dedicated line from construction point of view, puts forward key construction technology countermeasures, and further studies and solutions are needed Construction technology issues to be explored.
