Multi-dimensional treatment structure for deep soft soil roadbed

The embodiment of the utility model provides a multi-dimensional treatment structure for a deep soft soil road foundation. The deep soft soil roadbed structure sequentially comprises a first soft soil layer, a second soft soil layer, geotechnical cloth, a broken stone cushion layer, a block stone layer, a gravel cushion layer, a cement stabilized broken stone layer, a cement mortar bonding layer and a surface layer composite material plate from bottom to top. In addition, the system further comprises drainage blind ditches, water collecting wells, drainage plates, micro piles and drainage ditches. The roadbed structure comprehensively adopts principles and technologies of dynamic consolidation drainage, rigid support and a flexible surface layer, and dynamic consolidation drainage comprises a vertical drainage system and a horizontal drainage system. The rigid supporting effect of the micro piles can improve the bearing capacity of soft soil and reduce the deformation of an upper-layer structure of a roadbed.
