The invention discloses a foundation pit excavation zoning method considering soil anisotropy, which belongs to the technical field of building construction and comprises the following steps: step 1, layering soil in a set area around a foundation pit; step 2, acquiring various parameters; in the middle clay layer, soil anisotropy is considered, and the ratio of the plane strain passive shear strength to the plane strain active shear strength in soil layer parameters is valued in a first set range; 3, establishing a numerical analysis model; 4, numerical simulation is conducted, specifically, an upper clay layer and a middle clay layer are simulated through an anisotropic constitutive model, and a lower clay layer is simulated through a Mohr-Coulomb constitutive model; 5, analyzing and calculating the two-dimensional numerical analysis model to obtain a displacement field; and step 6, dividing influence partitions according to the displacement field. As the anisotropy of the soil body is considered, the actua
