本文将专家的经验分类标准与需要评判的围岩,用模糊数学中择近原则的方法进行模糊模式判别。对专家评判中的有关因素采用因素关系图描述。将被评定的围岩视为论域上的一个模糊子集,把推理过程抽象为多维论域上确定隶属度的过程,进而提出用连续隶属函数进行围岩类别的模糊推理。最后,以隶属度的形式给出评判的分类结果。
In this paper, the experts’ experience classification criteria and the surrounding rock that need to be judged are used to determine the fuzzy model by using the principle of nearest principle in fuzzy mathematics. The relevant factors in expert judgement are described using the factor relationship diagram. The assessed surrounding rock is regarded as a fuzzy subset on the universe of discourse. The reasoning process is abstracted as the process of determining the degree of membership on the multidimensional domain, and then the continuous membership function is used to conduct the fuzzy inference of the surrounding rock category. Finally, the classification result of the judgement is given in the form of membership degree.
