隧道结构病害机理及理论量化方法

以辽宁省内高速公路隧道定期检测资料为基础，对隧道衬砌既有结构病害的分布特征与规律进行归纳.在深入研究隧道主要结构病害的基础上，采用可拓学理论，提取数个能准确反映结构健康状态的指标，进行量化分级并建立相应的物元模型，从而确定各指标所占权重以及隧道结构病害等级，将衬砌结构病害定性评价与定量研究相结合，构建隧道衬砌结构健康状态评价体系，方便管理者做出合理决策.同时结合隧道工程实际检测数据进行可拓模型的计算分析，验证模型的工程适用性.

Disease Mechanism and Theoretical Quantification Method of Tunnel Structure

The distribution characteristics and laws of existing structural defects of tunnel lining are summarized based on the regular inspection data of expressway tunnels in Liaoning Province. On the basis of in-depth study of the main structural diseases of the tunnel， the extenics theory is used to extract several indicators that can accurately reveal the health status of the structure， to quantify and classify the health status， and to establish the corresponding matter-element model， so as to determine the weight of each indicator and the grade of tunnel structure disease. A health evaluation system for tunnel lining structure is constructed by combining qualitative evaluation and quantitative research， which is convenient for managers to make reasonable decisions. At the same time， based on the actual test data of tunnel engineering， the calculation and analysis of the extension model are carried out to verify the engineering applicability of the model.
