| Popis: | 91 This paper presents a seismic wave energy-based method with back-propagation networks to assess the liquefaction probability. The empirical equation and Fourier spectrum are employed respectively to calculate the seismic wave energy. The discriminant analysis is used to determine the equation in separating the cases with and without liquefaction. The results reveal that the proposed method shows capability in evaluating the probability of soil liquefaction based on the established boundary line and the application of logarithm normal distribution. Furthermore, the geography information system is utilized to geographically present the liquefaction potential and the maps compare favorably to in situ liquefaction areas induced by 1999 Chi-Chi earthquake in central Taiwan. |
