ZHU YANPENG / ZHAO ZHUANGFU / WU LINPING / LYU XIANGXIANG / YE SHUAIHUA

The invention discloses a supporting structure for a fill slope and a construction method thereof. An anchor cable anchoring unit and a prestressed anchor cable control unit of the supporting structure both comprise supporting units, and the supporting unit of the anchor cable anchoring unit and the supporting unit of the prestressed anchor cable control unit are arranged in parallel in a front-back row mode; one end of an anchoring steel strand of the anchor cable anchoring unit and one end of a prestressed steel strand of the anchor cable anchoring unit are both fixed in a slope body on thesame side of the slope; the other end of the anchoring steel strand is fixedly tensioned on a fastening steel plate, and the fastening steel plate is fixed to a steel pipe pile of the anchor cable anchoring unit; and the other end of the prestressed steel strand of the prestressed anchor cable control unit is fixedly tensioned on a top beam of the anchor cable anchoring unit, and the middle of theprestressed steel strand is erected on a top beam of the prestressed anchor cable control unit. The supporting structure has high engineering practical value and important social and economic benefits and is worthy of large-scale application and popularization.

本发明公开了一种填方边坡支护结构及其施工方法。该支护结构的锚索锚固单元以及预应力锚索控制单元均包括支护单元，锚索锚固单元的支护单元与预应力锚索控制单元的支护单元呈前、后排平行设置；锚索锚固单元的锚固钢绞线一端、预应力钢绞线一端均固定在边坡的同侧坡体内；锚固钢绞线另一端固定拉紧在紧固钢板上，紧固钢板固定在锚索锚固单元的钢管桩上；预应力锚索控制单元的预应力钢绞线另一端固定拉紧在锚索锚固单元的冠梁上，且该预应力钢绞线中部架设在预应力锚索控制单元的冠梁上。本发明支护结构具有较强的工程实用价值、重要的社会和经济效益，值得大范围推广应用。
