摘要
相比传统的可拓评价方法,引入了信息熵权和关联变换⑴的概念,结合模糊理论建立了可拓评价模型⑵,从而更好地解决了只能通过不完全的因素来评价岩体质量的矛盾问题,并在某两长大隧道围岩质量的评价中,取得了较好的效果。
Compared to traditional extension assessment method, this paper introduces information entropy weight and connection transformation into it and a new extension assessment model is established by combination with fuzzy theory. So it solves well the contradictory question about the assessing surrounding rock quality of tunnel by incomplete factors. Then this method is applied to two projects. The application result shows that the method is effective and practical.
