摘要
为了评价公路隧道围岩质量好坏,建立隧道围岩质量的评价系统和评价等级标准。引入集对分析法(SPA)对隧道围岩质量进行定量分析,选取评价指标,同时考虑层次分析法(APH)中同层次指标之间的相互影响,采用DEMATEL法修正指标权重,从而确定评价指标的最终权重,提高了指标权重的客观性和科学性。运用该评价模型对某高速公路的四个路段的隧道围岩进行验证,结果表明:该模型具有较高的评价精度,且评价结果合理、科学,符合现场实际情况,可推广至各类公路隧道围岩评价中应用。
In order to evaluate the quality of surround rock of highway tunnel, the evaluation system and rating standard of quality of highway tunnel surround rock was established. The quality of surround rock was quantitatively analyzed by introduction of set pair analysis （SPA） , selection of evaluation indicators and the weights of evaluation indexes were determined by using analytic hierarchy process （AHP）. This model was applied to evaluate the quality of surround rock of highway that select four tunnels. The results show This model has high accuracy evaluation, and evaluation results were reasonable and scientific, accord to the actual situation, the application can be extended to evaluation the quality of various highway tunnel surround rock.
