【摘要】：基于DERU评定方法建立改进的DES综合评价方法,主要用于运营公路隧道土建结构定期检查的技术状况评定。根据运营公路隧道土建结构技术状况评定的要求,构建包括目标层、准则层、指标层的评价指标体系,其中以隧道构件的D结构劣化破损程度、E劣化范围与S安全程度为指标层评价指标,并提出对应的判定标准和指标权重。按照隧道分段、分幅、整体的次序,建立相应步骤的评价方法,分别采用状况指标、优选指标、安全程度折算长度等指标,在隧道定期检查结果的基础上对隧道土建结构的技术状况进行综合评定,并给出评定结果的分析方法和等级划分界限值。该方法能对运营公路隧道的管理、检测、养护等工作提供更为充分的信息,提高相关工作的效率。
[Abstract]:Based on the DERU evaluation method, an improved DES comprehensive evaluation method is established, which is mainly used to evaluate the technical status of the regular inspection of the civil structure of the operating highway tunnel. According to the requirements of the technical evaluation of the civil structure of the operating highway tunnel, the construction includes the target layer. The evaluation index system of the criterion layer and the index layer, in which the damage degree of the D structure and the safety degree of S are taken as the evaluation indexes of the index layer, and the corresponding criterion and the index weight are put forward, according to the tunnel segment, the damage degree of the D structure and the safety degree of S are taken as the evaluation indexes. Setting up the evaluation method of the corresponding steps, adopting the condition index, the optimal selection index, the safety degree conversion length and so on. On the basis of the regular inspection results of the tunnel, the technical condition of the tunnel civil structure is comprehensively evaluated, and the analytical method and the grade limit value of the evaluation result are given. The method can be used for the management and detection of the running highway tunnel. Maintenance and other work to provide more adequate information, improve the efficiency of related work.
