摘要
结合四川江边电站引水隧洞,根据国内外已有的多种岩爆判据,选取了多个评价指标,以粗糙集理论中的属性约简和条件属性权重计算为基础,建立该隧洞岩爆预测的可拓评价模型,得到了引水隧洞多个洞段的岩爆等级,并与这些洞段的实际岩爆发生情况进行对比分析。结果证明,该方法的评价结果与实际情况较为吻合,对后期施工有较好的指导作用。
According to Riverside Hydropower Station diversion tunnel,selected several evaluation indicators from rockburst prediction criteria which had existed at home and abroad,based on attribute reduction and condition attribute weights calculation of rough set theory,established an extension evaluation model of rockburst prediction and got rockburst degree of diversion tunnel sections.It is approved that the evaluation results is consistent with the actual situation well,and it can play a very good guide for latter construction.
