粘性土边坡破坏的随机模糊可靠度分析模型

Model of Random fuzzy confidencelevel analysis on clayey soil slope

研究表明粘性土坡具有空间变异性，它的力学参数ｃ、φ值具有随机性和模糊性的双重特征。因此，标识边坡稳定性的稳定性系数具有随机模糊性。本文将统计分析、模糊数学和边坡破坏的可靠度理论结合起来，建立了粘性土坡破坏的随机模糊可靠度分析模型，并导出了相应的计算公式。

Studies show that clayey soil slope has the space variation,and its mechanical parameters c and φ are both random and fuzzy,so the stability coefficients possess the property of random and fuzzy in this paper,by combining the statistic analysis and the fuzzy mathematics with the theories of confidence level of slope failure,the model of random fuzzy confidence level on clayey soil slope is established,and the relative formulas are deduced also.
