Low shallow cut soil property ground roadbed structure that fills out of high -speed railway to realize that roadbed structure has enough intensity, rigidity, and can satisfy high -speed railway and strictly warp the requirement. It includes: the composite foundation sets up the shallow layer at the soil property ground, the bed course sets up at the composite foundation top, road bed foundation bed structure, layered filling is on the bed course top, pre -compaction soil is piled and is carried on road bed foundation bed structure top, the escape canal sets up in road bed foundation bed structure both sides. 高速铁路低填浅挖土质地基路基结构，以实现路基结构具有足够强度、刚度，并能够满足高速铁路严格变形要求。它包括：复合地基，设置在土质地基的浅层；垫层，设置在复合地基顶部；路基基床结构，分层填筑在垫层顶部之上；预压土，堆载在路基基床结构顶部之上；排水沟，设置在路基基床结构两侧。
