Abstract：The shaking table test of soil-structure interaction(SSI) is introduced. It includes the earthquake- wave-input large table tests and sine-wave-input small table tests. The structure and the subsoil are uniformly distributed；and one direction horizontal seismic waves are input. The dynamic stresses and pore pressures at symmetrical places under the structure and the differential settlement at symmetrical vertexes of the structure are achieved. Results show that：(1) the vertical dynamic stress histories are easily taken with the antisymmetrical distribution in the two sides of the symmetrical foundation；(2) the vertical dynamic pressing stresses in the two sides of the symmetrical foundation are very important for increase of pore-pressure；(3) the asymmetry of the seismic waves bring unbalanced distribution and differential settlement；and (4) when inputting sine-wave，the contrasts of dynamic stresses and pore pressures at symmetrical places under the structure are not obvious；and the uniform settlement will happen.
