岩石的坚固程度受多种复杂因素影响,常常表现出“亦此亦彼”的性质,也就是说,岩石的“坚固”概念具有模糊性。用以往的综合评分方法对岩石坚固性分级,无法反映这种模糊特性。难以给出较为满意的结果。本文试用模糊数学的方法,把岩石的凿岩爆破坚固性的优劣看作是岩石的凿岩爆破坚固性这一论域U的模糊子集A,构造了一个多元隶属函数,提出了一种模糊模型的分级方法。
Rock solidity is affected by many complicated factors, often showing the “also so” nature, that is, the concept of “solid” rock ambiguity. With the previous comprehensive grading method of rock solidity grading, can not reflect this fuzzy characteristics. Difficult to give more satisfactory results. In this paper, the method of fuzzy mathematics is used to consider the pros and cons of the rock drilling blasting robustness as the fuzzy subset A of the domain U of the rock drilling blasting robustness. A multivariate membership function is constructed and a Fuzzy model classification method.
