Abstract

The invention discloses a method, a system and a storage medium for determining the reduction of the horizontal resistance coefficient of a finite soil body. The method includes: establishing a semi-infinite soil layer model and an actual finite soil layer model; determining the semi-infinite soil layer model and the actual finite soil layer model Soil mass nodes that need to calculate the horizontal resistance coefficient; apply a uniform load to the soil mass nodes; calculate the reduction coefficient of the soil mass horizontal resistance coefficient on the soil mass nodes; calculate the soil mass horizontal resistance coefficient according to the reduction coefficient . Compared with the existing method of estimating the horizontal resistance coefficient of soil through the Winkel foundation model, the present invention can be applied to the situation of limited soil and complex boundaries, improves the accuracy and is easy to implement, and can be widely used in construction engineering technology field.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method, system and storage medium for determining the reduction of the horizontal resistance coefficient of finite soil. Background technique [0002] In the construction of building foundation pits or wading projects, reinforcement methods such as pit reinforcement or cofferdam dredging and filling sand, riprap, etc. are often used. Among them, when calculating the support structure in engineering construction, it is necessary to know the horizontal resistance coefficient of the soil. [0003] The traditional method uses the Winkel foundation model to study the deflection curve under the joint action of lateral load and supporting lateral soil resistance, and then the structural bending moment, shear force and deformation can be obtained. k in Winkel's foundation model h It is called the horizontal resistance coefficient of the soil, or the horizontal subgra...
