摘要
本文以Seed和Idriss简化法为机率分析法的基础,利用模糊讯息分析的基本理论并考虑砂性土基本动态特性所建立的模糊关系,进行砂性土液化潜能评估。计算结果与机率分析及蒙地卡罗模拟法结果互相对比、验证,表明模糊讯息分析对砂性土液化潜能可提供明确评估。
This paper describes some probabilistic analysis based on the simplified method suggested by Seed and Idriss and uses the fundamental theory of fuzzy information analysis for evaluating the liqufaction potential of sand. The basic dynamic characteristics of sand was considered for establishing the fuzzy relationship. The analytic evaluation was compaved and verified with methods of the advanced second order moment and Monte Carlo simulation A conclusion is obtained that the fuzzy information analysis can provide an accuate and objective evaluation of liquefaction potential of sand.
