围岩稳定性分级是地下工程学科研究的重点内容。属性识别理论是近年来提出的一种数学模型,通过将此模型引入到地下工程围岩质量分类评价中,建立了基于属性识别理论的地下工程围岩稳定性分级模型。结合工程实例验证了该模型,并与灰色优化理论模型分类的结果进行了对比。研究结果表明,此模型应用于地下工程围岩稳定性分级是可行的并有其优越之处。
Surrounding rock stability classification is the key content of underground engineering research. Attribute recognition theory is a mathematical model proposed in recent years. By introducing this model into the evaluation of surrounding rock mass classification of underground engineering, the stability classification model of underground engineering surrounding rock based on attribute recognition theory is established. The model was verified with the engineering example and compared with the gray classification theory. The results show that it is feasible and has its advantages to apply this model to the stability classification of surrounding rock in underground engineering.
