摘要
综合考虑了边坡平边滑动的随机性和模糊性。根据工程实际确定结构功能函数的概率密度函数及表征边坡稳定性的隶属函数,提出了边坡失稳的模糊概率和边坡稳定性模糊可靠度的计算方法,并计算了模糊可靠度的置信区间,具有一定的实际意义。
Randomness and fuzziness of plane sliding of slopes are considered comprehensively. Associating with real project condition, probability density function for performance function and membership function of the slope are set up. Then a practical method to calculate fuzzy failure probability and fuzzy reliability of slope’s stability is put forward. At the same time, confidence interval of fuzzy reliability is calculated.
