区间非概率可靠性方法的设计思想有时可能会过于保守而出现无谓增加工程造价的情况,从而导致区间非概率可靠性方法的适用性存在问题。为此,引入概率理论和蒙特卡洛法,得到区间非概率可靠性方法适用性评价指标,从而建立出区间非概率可靠性方法适用性的研究方法。结合实际工程,探讨区间非概率可靠性方法在岩溶区稳定性分析中是否会出现适用性问题,并研究具有区间不确定性的自变量变化幅度、自变量个数以及函数类型对区间非概率可靠性方法适用性的影响规律。研究表明,当自变量的变化幅度较大且自变量个数较多时,区间非概可靠性方法的适用性存在明显不足,相关研究结论能够为区间非概率可靠性方法的应用提供参考。
The design idea of interval non-probabilistic reliability method may sometimes be too conservative and there is a case of unnecessarily increasing the construction cost, which leads to the problem of the applicability of the interval non-probabilistic reliability method. Therefore, by introducing the theory of probability and Monte-Carlo method, the evaluation index of the applicability of interval non-probabilistic reliability method is obtained, and the research method of applicability of interval non-probabilistic reliability method is established. Combining with the actual project, this paper discusses whether the interval non-probabilistic reliability method will have applicability problems in karst area stability analysis and studies the variation range of variables, the number of independent variables and the type of function to the interval non-probabilistic reliability The Influence Law of Applicability of Sex Method. The research shows that the applicability of the interval non-probabilistic reliability method is obviously insufficient when the variation of the independent variables is large and the number of independent variables is large. The relevant research conclusions can provide reference for the application of interval non-probabilistic reliability methods.
