A method for calculating the structure of L-shaped retaining wall by using a spring support

Abstract

The invention provides a method for calculating the structure of an L-shaped retaining wall by using a spring support, which comprises the following step of: integrally calculating the L-shaped retaining wall according to a calculation section, namely integrally calculating a vertical wall, a bottom plate and a foundation of the retaining wall. The retaining wall foundation is simulated by adopting the spring supports, various different foundations such as natural foundations, pile foundations and composite foundations are simplified into different spring supports by utilizing the relationshipof stress and deformation of the foundation under the action of designed load, and the rigidity of the spring supports is calculated according to the additional stress and settlement of the foundation. In engineering application, a scientific analysis means is provided for the rationality of the design of the L-shaped retaining wall, a pile foundation or a soil body is simulated by the spring, acalculation chart is convenient to determine, force transmission and stress are clear, and a designer can use the device conveniently; through a plurality of engineering design tests, the method has good accuracy. A problem solving method is provided for engineering design, and continuous improvement of the hydraulic theory is facilitated.

Description

Technical field [0001] The invention relates to the field of hydraulic structure design, in particular to a method for simulating an L-shaped retaining wall structure calculation using a spring support. Background technique [0002] The L-shaped retaining wall refers to a retaining wall composed of an upright cantilever wall and a horizontal bottom plate. In the project, it is usually called a retaining wall composed of three reinforced concrete cantilever members: vertical wall, toe board, and heel board. This type of retaining wall has the advantages of simple section and convenient construction. It is one of the commonly used light retaining walls in current engineering and is widely used in water conservancy and municipal engineering. For example, most of the river bank revetments in Shanghai are L-shaped retaining walls. Especially in urban flood control and river improvement projects, they are often the preferred structural form, and their design directly affects the safety...

AI Technical Summary

Problems solved by technology

However, the retaining wall is placed on the elastic foundation, and the internal force calculation error of the conventional structural mechanics method is relatively large, and the internal force of the nodes is also unbalanced, which is unsafe for the project
