摘要
本文分析了边坡稳定性评价的概率方法中存在的不合理性。指出其中不但存在随机因素,还存在有模糊不确定因素。提出了边坡失稳破坏是一模糊事件的新观点。强调边坡稳定性评价应采用概率统计和模糊数学相结合的方法,得出边坡稳定性评价的模糊破坏概率模式,并应用于江西德兴铜矿大山村高边坡的稳定性评价中。
This paper analysed the unreasonable factors in probability statistics used to evaluate the stability of a slope. Among these factors there are not only random but also fuzzy indefinite factors. A new point of view that the failure of slope is a fuzzy event is put forward. The method of combining prboability statistics with fuzzy mathematics should be applied to the evaluation of the stability of slope so that the model of fuzzy failure probability for evaluation of the stability of a slope can be frigured out and it can also be used to evaluate the stability of the high slope at Dashang village in Jianxi Daxing Copper-ore.
