Granular mixture slope prevention and control design optimization method

Abstract

The invention discloses a granular mixture slope prevention and control design optimization method. The method comprises the following steps that: S1, impact influence factors of different gliding characteristics of granular mixtures on a slope blocking structure are analyzed; S2, a relational expression between a granular mixture impact force peak value and granular mixture impact conditions is constructed; S3, three different slope blocking structures are selected; S4, a granular mixture slope in the target area is selected, and granular mixture impact conditions of the granular mixture slope are measured; S5, the impact force peak values Fmax1, Fmax2 and Fmax3 of the three blocking structures bearing the granular mixtures in the target area are calculated; and S6, a blocking structure suitable for the granular mixture slope is selected according to the impact force peak values Fmax1, Fmax2 and Fmax3. The material strength can be brought into full play, it is ensured that the blocking structure can stably play a role, and reasonable selection can be conducted on the economic aspect and the safety aspect.

Description

technical field [0001] The invention relates to the technical field of prevention and control of geological disasters, in particular to a design optimization method for the prevention and control of granular slopes. Background technique [0002] At present, the construction and development of mountainous areas have attracted widespread attention from the international community, and my country is a mountainous country with mountainous areas accounting for 67% of the country's land area, and the population in mountainous areas accounts for 56% of the total population of the country. The prevention and control of disasters directly affects the economic construction and development of mountainous areas. Landslides, collapses, and debris flows are the most common geological disasters in mountainous areas, and another geological disaster—particulate slope disasters also has a very important impact. The granular slope refers to the slope body formed by the accumulation of the same...

Problems solved by technology

Since the granular slope has the characteristics of loose structure, high compression, strong water permeability, and low cohesion, it is similar to a plate of "loose sand". After instability, it is very easy to damage the blocking structure and engineering facilities, which is harmful to residents' property, life safety and traffic. Serious threats to security operations
