Abstract

The invention discloses a double-lug-wall integrated open cut tunnel structure. The structure comprises side walls and an arch part located at the upper ends of the two side walls, the arch part is ofa reinforced concrete structure, the upper end of each side wall is provided with a lug wall, the lug walls are of a reinforced concrete structure, backfill bodies are arranged in the areas between the arch part and the two lug walls, a bearing platform structure is arranged at the lower ends of the two side walls, the bearing platform structure and the side walls are integrally arranged, drilledpiles are distributed at the lower end of the bearing platform structure, the lower ends of the drilled piles extend into bed rock, and the upper ends of the drilled piles and the bearing platform structure are integrally arranged. The double-lug-wall integrated open cut tunnel structure uses a pile foundation and bearing platform integrated open cut tunnel structure, so that the problem that a structure foundation is suspended can be effectively solved, the structure can be better adapted to complex terrains, the impact load of dangerous rock falling can be effectively resisted, the stress effect is better, the construction difficulty is effectively reduced, the structure is simple and light, and the engineering cost can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to an integral open hole structure with double ear walls. Background technique [0002] With the rapid development of railway tunnel construction in my country, the construction scale of tunnel projects is also increasing day by day, and the operational safety risks brought about by it are also increasing. is especially important. However, in the mountainous area of ​​southwest my country, due to the influence of the terrain, the situation of adjacent bridges and tunnels and bridge abutments also widely exists. [0003] When the topography of the tunnel entrance is relatively steep, there are many dangerous rocks or rockfall hazards on the upward slope, and it is necessary to extend the open tunnel or shed tunnel. The traditional open tunnel structure is complex and difficult to solve the suspension problem of the bridge and tunnel foundation, and the force effect is poor...
