Pile-arch combined retaining structure and construction method thereof
The invention relates to the technical field of slope and landslide support, and particularly relates to a pile-arch combined retaining structure and a construction method thereof. The pile-arch combined retaining structure comprises a plurality of anti-slide piles which are vertically arranged in parallel, wherein the lower ends of the anti-slide piles are embedded into stable bed rock at the bottom of a slope; an arch-shaped structure is arranged between every two adjacent anti-slide piles; the outer arc surface of each arch-shaped structure faces the free side of the slope; two arch feet ofeach arch-shaped structure are fixedly connected with two adjacent anti-slide piles respectively; and an inter-arch unloading platform is fixedly arranged between the outer arc surfaces of every twoadjacent arch-shaped structures. The pile-arch combined retaining structure has the beneficial effects that the advantages of the arch-shaped structures are fully utilized, horizontal soil pressure isconverted into radial pressure of the arch-shaped structures, and finally the pressure of the arch-shaped structures is transmitted to the anti-slide piles; and the unloading platforms are arranged between the arch-shaped structures, so that the overall rigidity and the anti-overturning moment of a retaining wall are increased, the distance between the anti-slide piles can be greatly increased, the number of the anti-slide piles is greatly reduced, and the reliability of a support structure system is improved.
本发明涉及边坡及滑坡支护技术领域，尤其涉及一种桩拱联合支挡结构及其施工方法，包括多个并列且竖直设置的抗滑桩，所述抗滑桩的下端嵌固在边坡坡底稳定基岩中，相邻的两个所述抗滑桩之间均设有呈拱形的拱形结构，所述拱形结构的外弧面朝向边坡临空侧，所述拱形结构的两个拱足分别与相邻的两个所述抗滑桩固定连接，相邻的两个所述拱形结构的外弧面之间均固定设有拱间卸荷平台。本发明的有益效果是：充分利用拱形结构的优势，将水平土压力转换为拱形结构的径向压力，最终拱形结构压力传递给抗滑桩，在拱形结构间设置卸荷平台，增加挡墙的整体刚度与抗倾覆力矩，抗滑桩间距可大大增加，极大减少抗滑桩数量，提高了支护结构体系的可靠度。
