高速铁路路基碎石垫层与板筏施工工艺

Construction Technology of Gravel Cushion and Raft Structure for Subgrade of High-speed Railway

京沪高铁德州东站路基在地基处理时,桩顶由桩网结构调整为桩板结构,对工期提前和沉降总体控制起到了良好作用。详细介绍了碎石垫层+板筏施工工艺。

Based on foundation treatment for subgrade of Dezhou East Station of Beijing-Shanghai highspeed railway,pile-plank structure is used instead of column-net structure at pile top,which takes effect for shortening the construction period and overall settlement control. This paper introduces the construction technology of gravel cushion + raft structure for subgrade of high-speed railway.
