The shield construction safety in soft soil is always an important issue in engineering field. Based on the seepage-stress coupling theory, the evolution of soil permeability, the time-dependent stiffness and permeability of the grout material were modeled through second development on the platform of ABAQUS. The influence of cover depth, ground water level and soil properties on the ground settlement was investigated numerically. The results showed that the influence of time-dependent stiffness and permeability of grout material on ground settlement is more obvious than that of strain-dependent permeability of soil. Cover depth, ground water level and soil properties have an impact on ground settlement, and the influence of elastic modulus of soil is the greatest among them.
