Side slope reinforcing method and structure

Abstract

The invention discloses side slope reinforcing method and structure. The side slope reinforcing method comprises a step of building a concrete anti-shear structure in a slope body. The side slope reinforcing method is characterized in that the concrete anti-shear structure is an integral structure comprising anti-shear tunnels, anchored tunnels and displacement inclined shafts, wherein the anti-shear tunnels and the anchored tunnels are formed through pouring; a plurality of layers of the anti-shear tunnels are arranged at intervals along the strike direction of a slip crack surface in a compressive-shear area of the slip crack surface as seen from the side surface of the concrete anti-shear structure, and each layer of the anti-shear tunnels all horizontally extend on the slip crack surface; a plurality of the anchored tunnels are arranged at intervals along the strike directions of the anti-shear tunnels on the selected anti-shear tunnels as seen from the front surface of the concrete anti-shear structure, and the anchored tunnels all penetrate through the anti-shear tunnels along the directions facing to the slip crack surface; and besides, the two layers of anti-shear tunnels are connected into an integer through a plurality of the displacement inclined shafts extending between the selected upper and lower layers of the anti-shear tunnels along the slip crack surface. The integer formed by the anti-shear tunnels, the anchored tunnels and the displacement inclined shafts through the pouring is suitable for treating a large-size rocky high-steep side slope with deeper burial depth on the slip crack surface.

Description

technical field [0001] The invention relates to the technical field of rock slope reinforcement engineering, in particular to a slope reinforcement method and a reinforcement structure. Background technique [0002] In complex rock slope engineering, unfavorable geological bodies such as deep faults, fissures and weak dikes are the main factors affecting slope stability, and their treatment technology is the focus and difficulty of rock slope engineering. At present, the reinforcement structures successfully applied in large-scale high and steep rock slope treatment projects mainly include the following types: [0003] With the development of anchor cable technology, a large number of anchor cables have been used for reinforcement in landslide prevention and control. This technology stabilizes the landslide by arranging several rows of anchor cables on the landslide body and applying a prestress to the landslide body. In addition, this technology will also use prestressed ...

Problems solved by technology

[0006] However, when multiple groups of joint fissures and various types of faults and dikes are developed inside the slope, an extremely complex slope structure may be formed, which may be affected by natural forces such as human engineering activities, rainfall, and earthquakes, and may cause slope failure. stable

If the width of the sliding surface is large, the strength is low, and the scale of the sliding body is large, traditional reinforcement measures such as anti-slide piles, anchor cables, shear holes or anchor holes are difficult to adapt to the treatment of such large-scale landslides.
