Abstract
Aiming at practice, the wave propagation in soil has been comprehensively studied on the basis of FEM analyzing model being established. An investigation has also been performed on how to solve the problems of simulating transient vibration in actual foundation with FEM, and the result of calculating to the real transient vibration of actual foundation with FEM software ANSYS agrees with that of measuring. The vibration variation in the ground and the uneven subsidence of the factory houses’ pillars, with and without barrier vibration isolation, are calculated by employing FEM. The results show that proper barrier isolation can diminish the ground vibration displacement but likely to magnify the dynamic stress and vibration frequency within a certain region, which would aggravate the uneven subsidence of the factory house pillars.
