摘要
根据底板突水影响因素的多样性、模糊性以及隔水层破坏的突发特点,引入突变理论,建立了底板突水危险性评判层次结构模型;基于专家评分法和梯形模糊分布解决了初始模糊隶属函数构造和取值问题,使取值更合理、可行;根据归一化公式量化递归运算和互补原则,计算总突变隶属函数值并确定底板突水危险性等级,从而对底板突水危险性做出评判;研究表明,将本方法应用于工程实践是可行的、合理的。
According to floor water bursting impacting factors diversity, fuzzy and aquifuge destruction suddenly occur characteristics introduced catastrophe theory and established floor water bursting hazard assessment hierarchy structure model. Based on expert grading method and trapezoidal fuzzy distribution have solved initial fuzzy membership function structure and valuing issue, made the valuing more reasonable and feasible. According to normalization formula quantized recursive algorithm and complementary principle, estimated total catastrophic membership function value and determined floor water bursting grade, consequently assessed floor water bursting hazard. The study has shown that the application of the method on project practice is feasible and reasonable.
