粗糙集理论在江边水电站岩爆预测中的应用

Application of roughness set theory in the prediction of rock burst at Jiangbian hydropower project

针对洞室岩爆预测问题,将粗糙集理论和模糊综合评判有机地结合起来,并将模糊评判中的权系数问题转化为粗糙集中属性重要性评价问题,建立了基于粗糙集理论的岩爆预测模糊综合评判模型。最后将该方法应用于江边水电站引水隧道岩爆预测,结果证明该方法是可靠的。

For prediction of tunnel rock burst, the fuzzy synthetic judgment is organically combined with the roughness set theory, the weight coefficient of fuzzy judgment is converted into evaluation of the importance of roughness set attributes, and a model of fuzzy synthetic judgment for prediction of tunnel rock burst is established on the basis of roughness set theory. The method is applied in prediction of rock burst in diversion tunnels of Jiangbian hydropower project, which proves that the method is reliable.
