Advance support active pressure reduction structure for side slope and construction method

Abstract

The invention discloses a side slope forepoling active decompression texture which comprises a forepoling structure, rock and soil mass of the forepoling structure and rock and soil mass to be excavated; wherein, a layer of flexible filler is filled between the forepoling structure and the rock and soil mass of the forepoling structure; the flexible filler has a function of allowing the rock and soil mass of the forepoling structure to make certain displacement to the outside of the side slope; the loaded static earth pressure is converted into active earth pressure, which achieves the purpose of reducing the pressure of the forepoling structure to the soil, thereby achieveing the purpose of reducing the pressure of soil actively. The invention also discloses a constructing method of a side slope forepoling active decompression texture. The invention has the advantages of turning the loaded earth pressure at rest of a forepoling structure to active earth pressure, high economic benefit, convenient construction, simple and practical property and high applicability.

Description

technical field [0001] The invention relates to a landslide control technology, in particular to an active decompression structure and a construction method for advance support of a slope. Background technique [0002] Landslide disaster is a common supergene geological disaster phenomenon, which is mainly caused by various natural external forces and human engineering activities, etc. The advanced support structure to treat artificial cut slopes is a new method adopted by the engineering field in recent years, but at present The design of advanced support structures still lacks a unified understanding and standard, and basically stays in the empirical stage. Since our country is still in the stage of increasing infrastructure construction, the construction of railways and highways in mountainous areas will inevitably encounter excavation of natural slopes, so advanced support structures are used to support them. The traditional advance support structure uses the support st...
