可拓方法在地下工程岩体质量评价中的应用

基于物元理论和关联函数,将可拓理论引入到岩体质量等级评价当中,建立了岩体质量评价的可拓模型.以RMR评价方法为基础选取能够反映工程特性的评价指标,对某矿山工程岩体质量进行了可拓理论评价,引入改进的AHP法求解指标权重,避免了权重求解过程中人为主观因素影响过多的弊端.通过与传统的RMR评价方法对比分析,证明将可拓学运用于岩体质量等级评价是合理可行的,且分级结果具有更加直观的特点.表4,参10.

Application of Extension Theory to Rock Mass Quality Evaluation of Underground Engineering

On the basis of matter-element theory and dependent function,the extension theory was applied to evaluate the rock mass quality,and an extension model for quality evaluation of rock mass was build. In view of the variety and complexity of the factors influencing rock mass quality,the factors reflecting the engineering characteristic were taken into account for evaluation based on RMR method,then taking some rock mass of a mine for example,the extension evaluations for rock mass quality were carried out. The weights of factor were calculated by using improved AHP method,which avoided the excessive effect of subjective factor of human in practices,and made the evaluation results more objective. Compared with the evaluation results by the traditional RMR method,the research indicates that the extension method is reasonable and feasible in the field of evaluating rock mass quality classification,and the results have the more intuitive characteristic. 4tabs.,10refs.
