Wall-pile-net composite foundation bearing embankment structure
The invention discloses a wall-pile-net composite foundation bearing embankment structure in the field of civil construction traffic engineering. The wall-pile-net composite foundation bearing embankment structure comprises a plurality of cement-soil mixing piles, a cement-soil shear wall, discrete pile bodies and a geogrid reinforced cushion layer, wherein the cement-soil shear wall is formed by meshing and overlapping a plurality of adjacent cement-soil mixing piles. The discrete pile bodies are located between the cement soil shear walls, the discrete pile bodies and the cement soil shear walls are the same in height, the geogrid reinforced cushion layers are laid on the discrete pile bodies and the top faces of the cement soil shear walls, and the embankment filling soil is laid on the geogrid reinforced cushion layers. When the embankment is built, the discrete pile bodies and the cement soil shear wall can improve the bearing capacity of the soft soil roadbed, and the discrete pile bodies can reduce the settlement difference of embankment filling. The geogrid reinforced cushion layer plays a role in restraining the displacement of the sliding body and increasing the pile-soil stress ratio. Therefore, the embankment is supported by the composite foundation in a wall-pile-net form, so that the stability of the embankment can be effectively improved and the operation safety of the embankment can be ensured on the basis of meeting the requirements of roadbed bearing capacity and settlement control.
本发明公开了土木建筑交通工程领域的一种墙‑桩‑网复合地基承载路堤结构，包括若干水泥土搅拌桩、若干相邻的水泥土搅拌桩咬合搭接形成的水泥土剪力墙、离散桩体、土工格栅加筋垫层。离散桩体位于水泥土剪力墙之间，离散桩体与水泥土剪力墙高度相同，土工格栅加筋垫层铺设于离散桩体和水泥土剪力墙顶面，土工格栅加筋垫层上方铺设有路堤填土。建设该路堤时，离散桩体和水泥土剪力墙能提高软土路基承载力，若干离散桩体能减小路堤填土沉降差。土工格栅加筋垫层起到约束滑体位移和增加桩土应力比的作用。由此，采用墙‑桩‑网形式的复合地基支承路堤，可在满足路基承载力和控制沉降要求的基础上，有效提高路堤的稳定性，确保路堤的运营安全。
