| 摘 要： | 岩体稳定性受多种不确定性因素的影响,不仅具有随机性,而且也具有模糊性,属于模糊概率的范畴,利用经典的模糊综合评判方法进行研究将会产生不合理的结果.在模糊概率理论的基础上,建立了一类新的岩体稳定性综合评价方法--模糊概率方法,并提出了模糊权重的概念,从而避免了权重取值带来的不确定性.结合所选取的5个影响岩体稳定性的因素,建立了这5个影响因素的隶属函数与模糊权重;利用此方法对某一地下岩体工程进行了分析,并与其他方法所评价的结果进行了比较,表明了该方法具有合理性与可靠性.

| Abstract: | The stability of rock mass is affected by many uncertain factors with random and fuzzy behavior and belongs to the fuzzy probability category.To assess the stability of rock mass with classical fuzzy comprehensive assessment methods may lead to incorrect results.Based on the fuzzy probability theory,a new comprehensive assessment method for the stability of rock mass(fuzzy probability evaluation method) is presented in this paper.The fuzzy weighted values are established to avoid the uncertainties in determ... |
