摘要
通过对地基液化评价模型建立过程中模糊不确定因素的分析,引入模糊模式识别理论建立各实测数据点隶属度,并通过LOGISTIC回归分析,导出液化概率评价方程,建立地基液化概率和液化安全系数的函数关系,为利用现场实测资料进行地基液化判别提供了简便、较为准确的新途径。
Through analyzing fuzzy and uncertain factors in the process of establishing foundation liquefaction valuation model, the author introduces fuzzy pattern recognition theory to establish each field measuring point＇s membership grade, educes liquefaction probabilistic observation equipment through LOGISTIC regression analysis, and establishes functional relation between foundation liquefaction probability and liquefaction safety factors, in order to offer a new convenient and accurate way for the judgment of foundation liquefaction probability by using field measuring data.
