Soft soil foundation reinforcing structure under high embankment
The invention discloses a soft soil foundation reinforcing structure under a high embankment. The structure comprises a ground beam which is arranged on a foundation and of which the top surface is flush with the surface of the foundation, side pile sets which are located below the two sides of the foundation respectively and are in rigid connection with the ground beam, and a middle pile set which is arranged in the middle of the foundation and located between the two side pile sets. A bearing plate is arranged at the top of the middle pile set, and a mattress layer is arranged between the bearing plate and the top of the middle pile set. A cushion layer is arranged between the top of each side pile set and an embankment. The structure is high in integrity, good in stability and easy to machine and manufacture, the manufacturing cost is saved, and the problem that under the action of high embankment loads, side piles in the composite foundation are prone to bending resistance weakening firstly and gradually lose strength under the action of transverse loads, so that composite foundation pile bodies are damaged successively, and consequently the whole roadbed is unstable is effectively solved. Meanwhile, the problems that the vertical bearing capacity safety reserve of the side piles is too high and the total settlement of the embankment center is relatively large due to the fact that high-strength piles are arranged at equal intervals in the embankment slope and the embankment center are solved.
本发明公开了一种高路堤下松软土地基加固结构，包括设置于地基上且顶面与地基表面平齐的地梁、分别位于地基两侧下方且与地梁刚性连接的侧桩组以及设置于地基中部且位于两侧桩组之间的中桩组，中桩组顶部设置有承载板，且承载板与中桩组顶部之间设置有褥垫层，侧桩组顶部与路堤之间设置有垫层；整体性强、稳定性好、加工制作简易和节约造价，有效的解决了在高路堤荷载作用下复合地基中边侧桩在横向荷载作用下容易首先发生抗弯能力弱化而逐渐失去强度，从而导致复合地基桩体发生相继的破坏造成路基整体失稳的问题；同时解决了路堤边坡和路堤中心采用相同间距布置高强度桩，导致边侧桩竖向承载力安全储备过高、路堤中心总沉降相对较大的问题。
