[0002] Soft soil generally refers to clay soil in a soft plastic or fluid plastic state with high natural water content, high compressibility, low bearing capacity and very low shear strength. Soft soil is a general term for a type of soil, not a specific type of soil. In engineering, soft soil is often subdivided into soft clay soil, silt soil, silt, peat soil and peat. Soft soil generally has the characteristics of thixotropy, rheology, high compressibility, low strength, low permeability, and unevenness. Therefore, soft soil geological survey is an important task in soft foundation reinforcement engineering;
