To investigate a process of reduction of effective stresses in a saturated sand layer during liquefaction the authors performed analyses and experiments as follows. Predictions of liquefaction of a sand layer were carried out using the effective stress method developed by Finn et al (1976). The analyses were carried out for several typical saturated sand layers and under several conditions of magnitude of base input acceleration. On the other hand dynamic tests of a saturated sand layer, using a vibrating soil bin in the laboratory, were performed to observe the development of pore water pressures in the layer. Comparing the characteristics of the results of the analyses with that of the experiments, it is found that the rate of the production of the excess pore water pressure, that is, the increment of the excess pore water pressure per unit time, is expressed as a function of the relative density of the sand and the rate of the increment of the amplitude of the acceleration. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
