EVALUATION OF LIQUEFACTION POTENTIAL IN TERMS OF SURFACE WAVE METHOD

摘要：

As one kind of ground failure, soil liquefaction often had been observed after strong earthquake. Now, in many countries, judgment of liquefaction potential is considered in seismic code, and the standard penetration tests (SPT) is usually performed for the soil liquefaction potential situation. But, according to the cost, limited time, unsuitable site condition, traditional method often couldnt meet the users demands. As an attempt, an alternate method in terms of Surface Wave Method (SWM) had been used in recent years. In this paper, based on the Niigata Chuetsu-Oki earthquake (M6.8, July 16, 2007), SWM method and further comparison with active method had been carried out for the valuation of liquefaction potential. Compared with the traditional method, SWM method is easy, inexpensively and nondestructive to evaluate liquefaction potential.
