中文摘要：

为了对高速铁路隧道结构状态进行评价,采用定性分析与定量分析相结合的方法,依据调研结果,建立了包含水及结构2项因素的现役高速铁路隧道结构状态三级评价体系,并采用层次分析法及物元理论给出了各级评价指标的权重计算方法及权重计算结果。基于单因素指标打分结果并采用模糊综合评价理论,提出了高速铁路隧道结构状态三级模糊综合评价方法,通过工程算例分析证明了所提方法的适用性。

英文摘要：

For evaluating structural state of high speed railway tunnel,combining qualitative analysis with quantitative analysis,and based on survey results,a three-level evaluation system was established,which could consider the two factors including water and structure. The analytic hierarchy process（ AHP） theory and extenics theory were applied to calculate the weights of evaluation indicators of all levels. Based on scoring results and fuzzy evaluation theory,a three-stage fuzzy comprehensive evaluation method for structural state of high speed railway tunnel was proposed. By applying it to an engineering example,the applicability of the proposed method was verified.
