基于特征树类比法的软岩巷道支护设计原理与应用

Principle and application of soft rock roadway support design based on characteristic tree analogy

根据从定性到定量综合集成法原理,提出了适用于复杂巨系统间相似性与差异性分析的特征树类比法及相关理论,并给出了特征树模型结构及定量计算相似性指数的计算机算法,以此为基础构建人机交互的类比分析体系。将特征树类比法原理应用到软岩巷道支护设计中,有效地解决了不同巷道断面之间的可类比性无法定量分析的问题。针对龙口矿区软岩巷道支护决策系统研究课题,基于特征树类比法原理开发了巷道支护设计决策支持系统,通过挖掘分析以往巷道的支护案例实现设计方案的类比迁移。工程实践表明该系统能够有效地实现类比对象检索、类比分析及设计方案咨询功能,验证了特征树类比法对于软岩巷道支护设计的适用性与可靠性。

Based on the principle of meta-synthesis,this paper proposed the characteristic tree analogy and relevant theories for the analysis of similarity and difference among complex giant systems,while the authors derived the characteristic tree model structure and algorithm of calculating the similarity index quantitatively.Hereby an analogy analysis system of human-computer interaction was established. The principle of characteristic tree analogy was applied to soft rock roadway support design,which effectively solved the problem that cannot analyze the comparability between different projects quantitatively.Taking the research of Liangjia coal mine soft rock roadway support decision system as an example,the decision support system of roadway support design was developed based on the principle of characteristic tree analogy and the analogical transfer was achieved by excavating and analyzing the existing roadway support cases.Engineering practice shows that the decision support system can effectively achieve the functions of analogical objects retrieval,analogy analysis and support design consultation,which verifies the applicability and reliability of the characteristic tree analogy for soft rock roadway support design.
