The invention discloses a method for compositely reinforcing a soft soil foundation. The method comprises the following steps that S01, a permeable layer is laid on the surface of the foundation, and foundation soil is consolidated through tamping; S02, reinforcing rib soil is prepared, the pit of the foundation is filled with the stirred reinforcing rib soil, and the reinforcing rib soil with the thickness of 10-25 cm is laid on the top face of the foundation soil; S03, a raft is arranged on the reinforcing rib soil, and the raft is connected with the reinforcing rib soil through a reinforcing structure at the same time; and S04, soft soil is packaged into bags, bag openings are tightened, and the soil bags are stacked up and down in a crossed mode and arranged on the surface of the foundation. The pit of the foundation is filled with the reinforcing rib soil, the overall structural strength of a soil body can be improved, the stress distribution of the soil body is improved, the bearing capacity of the foundation is improved, and foundation deformation is reduced; meanwhile, the raft is arranged and used for bearing the load from a roadbed structure, the strength of foundation soil is guaranteed, and the bearing and settlement control effect is effectively guaranteed.
本发明公开了一种复合加固软土地基的方法，包括以下步骤：S01、在地基表面铺设透水层，通过夯击使地基土产生固结；S02、制备加强筋土，将搅拌后的加强筋土填充到地基的坑内，在地基土的顶面上铺设10‑25cm厚度的加强筋土；S03、在加强筋土上设置筏板，将筏板同时与加强筋土通过加固结构连接；S04、将软土灌装入袋，袋口扎紧，上下交叉堆叠土袋布置在地基表面。本发明采用加强筋土填充到地基的坑内，可以提高土体的整体结构强度，改善土体的应力分布，提高地基的承载力，减小地基变形；同时通过设置筏板，筏板用于承受来自路基结构的荷载，保证地基土的强度，有效保证了承载和沉降控制效果。
