Near-landslide embankment anti-slip, sinking control and anti-dislocation reinforcing structure and construction method thereof
The invention discloses a near-landslide embankment anti-slip sinking control and anti-cracking reinforcing structure and a construction method thereof. The structure has the effects of resisting landslide pushing, controlling poor foundation settlement deformation and resisting embankment filling internal sliding cracking for a high-fill embankment which is adjacent to a landslide and located ona poor foundation. The reinforcing structure comprises an anti-slip foundation pile assembly, a sinking control foundation pile assembly, a bearing platform assembly, a cushion layer, an embankment and a protection pile assembly. The anti-slip foundation pile assembly comprises anti-slip foundation piles arranged at intervals in the line direction, and the anti-slip foundation piles are located onthe front edge of a landslide body and embedded into the sliding bed after penetrating through a potential sliding surface; the sinking control foundation pile assembly comprises sinking control foundation piles which are distributed at intervals in the direction of the cross section of the embankment and along the trend of a line; the bearing platform assembly comprises bearing platforms which are arranged at intervals along the direction of a line, and the lower surfaces of the bearing platforms are connected with the upper ends of the anti-sliding foundation piles; the cushion layer is filled above the controlled sinking foundation pile assembly and between the adjacent bearing platforms; the embankment is positioned over the cushion layer; and the protection pile assembly comprises protection piles arranged at intervals in the line direction, and the lower ends of the protection piles are fixedly connected with the upper surface of the bearing platform.
本发明公开了近滑坡路堤阻滑‑控沉‑抗错裂式加固结构及其施工方法，对邻近滑坡且处于不良地基上的高填方路堤具有阻抗滑坡推挤、控制不良地基沉降变形和抵抗路堤填土内部滑动错裂作用。该加固结构包括：阻滑基桩组件，包括沿线路走向间隔排列的阻滑基桩，所述阻滑基桩位于滑坡体前缘且穿过潜在滑面后嵌入滑床内部；控沉基桩组件，包括在路堤横断面方向上及沿线路走向间隔分布的控沉基桩；承台组件，包括沿线路走向间隔排列的承台，所述承台下表面与所述阻滑基桩上端连接；垫层，所述垫层填充于控沉基桩组件上方以及相邻承台之间；路堤位于垫层上方；防护桩组件，包括沿线路走向间隔排列的防护桩，所述防护桩下端与所述承台上表面固定连接。
