Abstract

The invention discloses a high-steep side slope subgrade structure for a mountain area, which is used for effectively lowering the construction cost of a subgrade in a high-steep mountain area and avoiding the huge potential safety hazard existing in the excavation of a high-steep side slope. The structure comprises reinforced concrete long column piles (1), reinforced concrete short piles (2), reinforced concrete trimmer beams (3) and a reinforced concrete road surface (4), wherein the reinforced concrete long column piles (1) are arranged at the outer side of a high-steep subgrade side slope and are longitudinally arranged at intervals along the subgrade; anchor ropes (5) anchored with bedrock are vertically arranged at intervals on the reinforced concrete long column piles (1); the reinforced concrete short piles (2) are arranged at the inner side of a high-steep subgrade excavation side slope and are correspondingly arranged at intervals in parallel to the outer side reinforced concrete long column piles (1) along the longitudinal direction of the subgrade; the reinforced concrete trimmer beams (3) are fixedly connected with the tops of every group of corresponding reinforced concrete long column piles (1) and reinforced concrete short piles (2); and the reinforced concrete road surfaces (4) extend along the longitudinal direction of the subgrade and are poured on each reinforced concrete trimmer beam (3).

Description

technical field [0001] The invention relates to a railway embankment, in particular to a roadbed structure with high and steep slopes in mountainous areas, so as to avoid huge potential safety hazards in excavating high and steep slopes. Background technique [0002] Road construction in mountainous areas has become one of the key conditions for economic development in mountainous areas. Due to the fragile geological environment and steep terrain in mountainous areas, the construction of a large number of tunnels and bridges will cost a lot. How to build subgrade engineering under such geological and topographical conditions has become an urgent research problem. It is urgent to invent a new type of subgrade structure that can not only ensure the safety of subgrade construction, but also reduce construction costs and meet environmental protection requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a roa...
