Pre-stressed anchor cable-reinforced earth retaining wall combined supporting and retaining structure and construction method thereof
The invention discloses a pre-stressed anchor cable-reinforced earth retaining wall combined supporting and retaining structure and a construction method thereof, and belongs to the technical field of roadbed supporting. The structure comprises a panel assembly, reinforced soil and a pre-stressed anchor cable; the panel assembly comprises a foundation, a breast board and rib columns, wherein the breast board and the rib columns are arranged on the foundation; the reinforced soil comprises filling soil and a plurality of geogrids arranged from top to bottom, the space between the panel assembly and the slope surface is filled with the filling soil, one end of each geogrid is connected with the soil retaining plate, and the other end of each geogrid extends to the slope surface; the pre-stressed anchor cable is connected between the panel assembly and the slope, a free section in the middle of the pre-stressed anchor cable inclines downwards from the panel assembly to the slope at an inclination angle of 2-4 degrees and does not intersect with the geogrid, and pre-stress of the anchor cable is transmitted to filling lateral pressure through the rib columns and the breast boards; the pre-stressed anchor cables are introduced into the reinforced earth retaining wall of the mountain slope section, and the problem of differential settlement of a roadbed under the long-term load effect is solved.
本发明公开了预应力锚索‑加筋土挡墙组合支挡结构及其施工方法，属于路基支护技术领域；包括面板组件、加筋土和预应力锚索；面板组件包括基础以及设置在基础上的挡土板和肋柱；加筋土包括填土与多个从上至下排列的土工格栅，填土填充在面板组件与斜坡坡面之间，土工格栅一端与挡土板连接，另一端延伸至斜坡坡面；预应力锚索连接在面板组件与斜坡之间，预应力锚索中间的自由段以2‑4°的倾角沿面板组件至斜坡向下倾斜且不与土工格栅交叉，锚索的预应力通过肋柱和挡土板传递给填土侧向压力；本发明将预应力锚索引入山区斜坡地段加筋土挡墙，解决了路基长期荷载作用下不均匀沉降的问题。
