基于模糊最优归类理论的岩体质量评价

Evaluation of Rock Mass Quality Based on Fuzzy Optimal Cluster Theory

介绍了模糊最优归类理论,并建立了围岩最优归类模型。在此模型基础上,对单轴抗压强度、节理条件、岩石质量指标、节理间距、地下水条件等围岩稳定性的影响因素进行指标权重优化。通过影响因素的权重优化,分析了失稳巷道围岩质量等级,并将结果与RMR法的分类结果进行比较,得出最优化模型,为后期的治理工作提供依据。

This paper introduces fuzzy optimal cluster theory,and establishes a fuzzy optimal cluster model for surrounding rock.Based on the model,the weight of the factors influencing the stability of surrounding rock,such as uniaxial compressive strength,the joint condition of rock,rock quality designation（RQD）,joint spacing,groundwater,is optimized.Next step,the surrounding rock quality of an unstable roadway is also assessed.The results obtained by the method are compared with that obtained by RMR method,and an optimal model can be obtained,it can provide a basis for the later treatment.
