Soft foundation loading control standard method based on stress path

The invention belongs to the technical field of engineering, particularly relates to a soft foundation loading control standard method based on a stress path, and aims to solve the problems that certain defects exist in the prior art, particularly theoretical insufficiency exists in selection of control standards, the following scheme is provided, and the method comprises the following steps that S1, loading safety coefficient analysis based on the stress path is carried out, in the preloading process, the shear strength of the soil body is continuously improved, the shear stress in the soil body is also continuously increased, and the circle radius of the shear stress is also increased, so that firstly, it is assumed that each stage of loading can reach a loading critical state, that is, the shear stress borne by the soil body is equal to the shear strength of the soil body, but the soil body is not subjected to shear failure; a loading safety coefficient calculation formula is established based on a soil st
