Aming at the problems occurring in static pressure pile-sinking in hard multi-layered soils, an analytical solution of spherical cavity expansion in concentric layered soil was developed based on unified strength theory, large deformation hypothesis and dilatancy of soil. The simulation results were compared with the ABAQUS finite element analysis to verify the correctness of the solution. The hard interlayer expansion difference were compared, and the influence factors for cavity expansion pressure in concentric layered soil and horizontal layered soil were discussed. The results showed that, the internal friction angle ratio had no significant influence on the interface influence distance. The cohesion ratio had significant influence on soil influence scope. The larger the cohesion ratio between hard interlayer and soft soil, the less interface influence distance was. With the increase of elastic modulus ratio, the soil layer affected scope had an increase trend, the soil strength of hard and soft radius ratio can't not reflect soil layer affected scope.
