| 摘 要： | 工后沉降控制是京沪高速铁路路基工程设计最核心的问题。针对京沪高速铁路徐州至上海段路基工程的特点，在分析沉降控制设计关键技术问题的基础上，提出适宜的工后沉降分析方法及主要沉降控制设计方案:采用CFG桩、预应力管桩及桩板结构等进行加固。经现场施工及典型工点的沉降观测、评估，验证了其可靠性、合理性，满足了铺设CRTSⅡ型板式无砟轨道要求。

| Abstract: | Post-construction settlement control is the key problem in subgrade engineering design of Beijing-Shanghai High Speed Railway.According to the characteristics of Xuzhou-Shanghai Section subgrade engineering in Beijing-Shanghai High Speed Railway,based on analysis of settlement control key technique,this paper puts forward a proper analysis method for post-construction settlement and the main control design program,i.e.reinforcement with CFG pile,prestressed pipe pile and pile-slab structure.Through observation and evaluation of typical point settlement in site construction,it is verified reliable and reasonable,which satisfies the requirement for paving CRTSⅡ type slab ballastless track. |
