摘要
传统边坡稳定性分析方法对于边坡稳定状态的判断，主要是基于工程经验和边坡稳定性系数定义的一种“点状态”的认识来进行的，导致实际的边坡设计中，边坡参数及边坡稳定性系数取值，由于各行业边坡的重要性及危害程度的不同，而存在很大的差别。本文基于模糊数学和边坡可靠度分析方法，提出采用模糊概率指标判断边坡稳定状态，同时以立洲水电站库区堆积体边坡为例，对此方法进行了进一步探讨。
Traditional slope stability analytical method for judge of slope stable condition is mainly based on the engineering experience and ＂ point state＂ of slope stability coefficient definition, which leads to a very big difference of slope parameter and stability coefficient value in the actual slope design as a result of the difference of the slope importance and ravages in each industry. This article proposes to use fuzzy probability indicator for judging slope stability condition, based on the analytical method of fuzzy mathematics and slope reliability and at the same time further discusses the method by taking the accumulation slope in the reservoir area of Lizhou Hydropower Project as an example
