摘要
基于物元模型和聚类分析,提出了围岩岩体质量分级的可拓聚类预测方法。先利用岩体质量等级和影响因子,构造经典域物元和节域物元,然后应用物元和可拓集合中的关联函数,建立围岩岩体质量预测等级模型,通过聚类分析,得到围岩质量分析的预测结果。结果表明可拓学模型预测性能良好,预测精度高,是围岩岩体质量分级预测的一种有效方法,可以在实际工程中进行推广应用。
Based on matter-element model and cluster analysis,an extension cluster prediction method for wall rock mass quality classification is proposed.In the method,the grade types and influence factors on rock mass quality are used to set up the classical and segment matter elements.A simple forecasting model of rock mass quality classification is established by applying the correlated functions of matter elements and extension sets.The predicting results of rock mass quality classification are obtained by applying cluster analysis.The results show that the prediction model of extension theory has excellent performance.This is a new method to predict wall rock mass quality classification and can be used in practical engineering.
