| 摘 要： | 以沪宁城际铁路客运专线为背景,在实测数据的基础上,通过预测计算分析,证明了桩板复合地基能有效地降低高速铁路无砟轨道路基结构的沉降,使其工后沉降量满足扣件的调整需要和线路竖曲线圆顺的要求,为正在建设的客运专线提供技术支持。

| Abstract: | Taking Shanghai-Nanjing Intercity Railway Passenger Dedicated Line for example,through prediction and calculation,it is proven from measured data that pile-slab composite foundation can effectively reduce the settlement of ballastless track substructure of high-speed railway,so that post-construction settlement can meet the requirement for fastener adjustment and smooth vertical curve of railway line. |

| Keywords: | high-speed railway pile-slab composite foundation substructure post-construction settlement |
