地下工程围岩质量分级的属性数学方法

摘要

The adjoining rock classification of underground engineering is an important part of the underground construction subject. The theory of attribute recognition as a mathematical model is presented in recent years. The model for adjoining rock stability classification of the underground engineering is presented based on the attribute recognition theory. Combined with the practical engineering, the model is applied. The result is compared with the grey optimal theory model. It shows that the proposed model is more reasonable.%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.
