Abstract

According to the existing test results, this paper further analyzes the distribution form of stress between the foundation slab and the soil. Based on the thin plate bending control equation, the disturbance and load are expanded into corresponding cosine function Fourier series, and combined with the boundary conditions of the foundation slab, the bending moment of the four-sided free square foundation slab on the elastic foundation under symmetrical load is solved. The finite element method is used to verify the obtained analytical solution. The finite element results show that the analytical solution proposed in this paper has high accuracy and can be used to solve the bending problem of foundation slab.
