Multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure and design and calculation method thereof

Abstract

The invention relates to a multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure and a design and calculation method thereof, and the multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure and the design and calculation method thereof are particularly suitable for the field of civil engineering construction of vast mountainous cities. The multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure provided by the invention comprises a bamboo reinforcement reinforced earth structure body, bamboo reinforcement and lime soil, and the bamboo reinforcement and the lime soil are arranged in the bamboo reinforcement reinforced earth structure body. The invention further provides the design and calculation method of the multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure. The method includes the following steps that a, the number of steps, the platform width, the slope gradient, the height of each step and the linetype of the slope surface are determined; b, proportions of the lime soil are calculated and bamboo reinforcement reinforced belts are manufactured; c, the fracture surface of a bamboo reinforcement reinforced body is determined; d, the soil pressure and cohesion of bamboo reinforcement earth are calculated; and e, design and layout of the bamboo reinforcement reinforced belts are carried out. The multistep high-slope and wide-platform type bamboo reinforcement reinforced earth structure and the design and calculation method thereof have the advantages that local materials can be utilized, safety, reliability, economical efficiency and practicability are achieved, construction is convenient, the environment-friendly and ecological performance is achieved, and the economic benefit and social benefit are quite superior.

Description

technical field [0001] The present invention relates to a multi-level high slope, wide platform bamboo-reinforced soil structure and its design and calculation method. , and its design and calculation methods are also different. This new bamboo-reinforced soil structure is particularly suitable for use in the civil engineering field where multi-level high slope support is required for large excavation and large filling areas in the industrial and traffic construction of vast mountainous cities and villages in my country. Background technique [0002] The soil retaining structure on both sides of the shoulder of mountain roads and railways or high fill slopes often adopts reinforced soil retaining structures. The slopes of reinforced soil structures in the prior art are generally vertical, and the slopes are made of reinforced concrete panels. , the reinforced belt is a steel-plastic composite reinforced belt, and the filler body of the reinforced body is sandy soil with goo...

Problems solved by technology

[0003] This design calculation method is not applicable to the case where the reinforced soil slope has a gentle slope rate, that is, a non-vertical panel, and is a multi-level, staggered multi-level high-slope bamboo-reinforced soil structure, and the current code stipulates: Reinforced soil structures with wall heights exceeding 20 meters require special design, which is not suitable for multi-level high-slope bamboo-reinforced soil structures with slope heights much greater than 20 meters
