Abstractfulltext

Soil liquefaction had been observed as a kind of ground failure 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 couldn’t meet the user’s demands. As an attempt, an alternate method in terms of Surface Wave Method (SWM) has been used in recent years. In this paper, based on the Noto-Hanto earthquake (M6.9, March 25, 2007) and 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.
