岩石坚固程度受多种复杂因素的影响,本文认为岩石的纵波速度、单轴抗压强度和凿碎比功是基本影响因素。由于岩石物理力学参数和上述三因素的相对重要性均存在较大的不确定性,建议将被评定的岩石坚固性等级视为等级论域上的一个模糊子集,并利用模糊数学中的模糊推理和综合评判的理论,提出了一个综合评定岩石坚固性分级的新方法。
The rock solidity is affected by many complicated factors. In this paper, it is considered that the longitudinal wave velocity, uniaxial compressive strength and the specific work of rock chiseling are the basic influencing factors. Because of the great uncertainty of rock physical and mechanical parameters and the relative importance of the above three factors, it is suggested that the rock solidity grade to be evaluated be regarded as a fuzzy subset in the domain of rank theory, and fuzzy in fuzzy mathematics Reasoning and comprehensive evaluation of the theory, put forward a comprehensive assessment of rock solid classification of new methods.
