Abstract: The time effect of soil deformation reflects the unification of soil consolidation and rheology, and that is, the soil rigidity itself has time effect. Through the analytical method, the rigidity matrix of building foundation considering time effect has been established; and thus the calculation of the rigid foundation is solved with program. The working mechanism of the rigid foundation, such as the contact pressure and deformation, has been demonstrated. Initially, the settlement and contact pressure of the foundation develop quickly in the beginning of loading, and then slow down. Along with the time growth, the settlement still increases, also, the contact pressure increases in the corner of foundation and decreases in the center, and gradually tends to be stable. Finally, the distribution curve of the counterforce acting on foundation is characteristic of a saddle-like shape, which is higher in the edges and lower in the center.

Key words: time effect, rigid foundation, contact pressure, settlement
