Dynamic consolidation has been used on a wide variety of soil types and conditions in recent ten years. However, its mechanism of improvement has not been fully understood yet. A simplified method for evaluating the degree of improvement is proposed in this paper based on the results of some triaxial compression tests. The triaxial tests under low and high confining pressures were performed, considering the magnitude of stress increments induced by falling weights. The change of void ratio of sand was related by the increment of mean principal stress and deviator stress, respectively. Combining the tests results with finite element method on in situ probelm, the change of void ratio, which is related to the improvement of ground, was evaluated in each element in the ground.
