全面介绍武广铁路客运专线乌龙泉至韶关段路基变形控制设计,阐述客运专线高标准的路基变形控制设计理念、方法与内容。提出无砟轨道路基变形控制设计的关键不仅要有准确的地质资料以及正确的土工参数,还关系到设计沉降估算方法的正确选取、设计沉降控制措施的合理选择、路基施工质量的控制、沉降监测系统与分析评估等各个方面。目前武广铁路客运专线已建成并经近1年的联调联试检验,成功地实现了变形控制要求。
This paper introduces the design of deformation control of the subgrade of Wulongquan-Shaoguan section of Wu-Guang Railway Passenger Dedicated Line and elaborates the design concept, method and content of high-standard subgrade deformation control of Passenger Dedicated Line. The key to the design of ballastless subgrade deformation control is not only accurate geological data and correct geotechnical parameters but also the correct selection of design settlement estimation method, reasonable selection of design subsidence control measures, subgrade construction quality control and settlement monitoring System and analysis of all aspects of assessment. At present, the Wuhan-Guangzhou Passenger Dedicated Line has been completed and has been successfully completed the requirements of deformation control by the combined test of nearly one year.
