摘要
结合某高速铁路工程实例,介绍了铁路路基碎石垫层+板筏的结构原理及特点,主要对该结构的施工工艺流程及技术要点进行了阐述,分析了施工质量控制措施,指出该工艺可有效降低路基沉降和不均匀沉降。
Combining with the engineering example of a high speed railway, this paper introduced the structure principle and characteristics of railway sub-grade gravel cushion ＋ raft board, mainly elaborated the construction process and technology key points of the structure, analyzed the construction quality control measures, pointed out that this technology could effectively reduce the sub-grade settlement and uneven settlement.
