Interception diversion anchoring slab-pile wall and design method thereof

Abstract

The invention relates to the technical field of landslide prevention and control, in particular to an interception diversion anchoring slab-pile wall and a design method thereof. The interception diversion anchoring slab-pile wall comprises multiple permeable piles, multiple interception walls arranged among the permeable piles and anchoring structures connected with the permeable piles. The interception diversion anchoring slab-pile wall can play an effect of supporting and retaining a deep-layer large-scale landslide, can also timely intercept and drain away underground surface water in a landslide mass, timely remove rock and earth mass pore water pressure, effectively lower rock and earth dead load, reduce rock and earth mass strength loss, particularly sliding surface strength loss, improve the anti-shearing strength of the rock and earth mass, prevent underground water from being infiltrated into a lower-level slip mass, is beneficial to stabilization of the lower-level slip massor even the entire slip mass, directly lower the sliding force of the earth mass behind the slab-pile wall, and improve the anti-slip capability of the sliding surface. In this way, in the design, the sectional dimension of the permeable piles can be reduced, the construction cost can be reduced, and the engineering economy benefit can be increased.

Description

technical field [0001] The invention relates to the technical field of landslide prevention and control, in particular to a water-cutting and diversion-type anchor-stayed pile-slab wall and a design method thereof. Background technique [0002] Landslides are one of the major geological disasters that threaten the development of mountainous areas in my country. The complex geological structure, high mountains and steep valleys, broken rock mass, concentrated rainfall and other conditions in mountainous areas of our country provide a series of favorable conditions for the formation of landslides. The occurrence of landslide disasters seriously threatens the safety of people's life and property, and restricts the sustainable development of mountain economy. Therefore, it is necessary to implement effective prevention and control measures for landslide disasters. [0003] The pile-slab wall has the advantages of simple structure, small amount of masonry, construction safety, m...

AI Technical Summary

Problems solved by technology

However, when the landslide body is rich in water and the thrust of the slope body is huge, the current pile-slab wall structure and the current conventional anti-sliding retaining structure have the problem of limited drainage capacity, so it is often necessary to increase the structural design size to achieve the instability of the retaining structure. The role of the slope, resulting in very expensive construction and later maintenance costs
