Embodiment Construction

[0045] The present invention is a method for calculating the side displacement of an arc-shaped connecting wall. The specific implementation is as follows: figure 1 As shown, the steps are as follows:

[0046] Step 1: first simplify the arc-shaped ground connection wall into a cylindrical shell, and then use the curvilinear coordinate system to specify its coordinate system, set the direction along the generatrix of the cylindrical shell as the α axis, set the direction along the circumference of the cylindrical shell as the β axis, The radial direction of the shell is the γ axis, such as figure 2 shown.

[0047] Step 2: According to the classical shell theory, the relationship between the strain and displacement of the arc-shaped ground connection wall is obtained as follows (1-1):

[0048] ϵ α = ∂ ...

Abstract

Provided is a method for calculating side displacement of an arc-shaped underground continuous wall. The method comprises the steps that the arc-shaped underground continuous wall is simplified as a cylindrical shell, a curvilinear coordinate system is established, the relationship between surface strain in the arc-shaped underground continuous wall and the displacement is established according to a classical shell theory, the relationship between stress of any point of the arc-shaped underground continuous wall and the displacement and a balance differential equation of any infinitesimal in the arc-shaped underground continuous wall are determined according to the Hooke's law, a balance differential equation of the arc-shaped underground continuous wall is deduced, and therefore the side displacement of the arc-shaped underground continuous wall is determined according to boundary conditions of corresponding working conditions.

Description

technical field [0001] The invention relates to a method for calculating the side displacement of an arc-shaped connecting wall, which belongs to the technical field of geotechnical engineering applications. Background technique [0002] In foundation pit engineering, due to the advantages of small construction vibration, high wall rigidity, good integrity and fast construction speed, the underground diaphragm wall is widely used in deep foundation pit excavation enclosure structure engineering. However, at present, there is no very good method for calculating the lateral displacement of the arc-shaped ground connection wall, which is only determined through numerical simulation and on-site monitoring. Contents of the invention [0003] The object of the present invention is that there is no good method for calculating the lateral displacement of the existing arc-shaped connecting wall, and the present invention proposes a method for calculating the lateral displacement of...
