Abstract
In view of severe control standard for post-construction settlement and deformation of express railway subgrade, large area of farmland taken by conventional subgrade, large area of base, high cost of foundation treatment, a new tray type U-shaped subgrade structure having feasible technology, economical rationality, good strength, stability and durability and the ability controlling subgrade deformation is studied to effectively control the deformation of subgrade on thick compressible foundation and reduce the cost for subgrade treatment and the area taken by subgrade engineering. It is the brand new concept for design of subgrade engineering structure.关键词
