基于AHP-Cloud方法的城中湖隧道关键适用技术绩效评价研究

Research on Performance Evaluation of Key Applicable Technology in Urban Lake Tunnel Based on AHP-Cloud Method

城中湖隧道是典型的复杂工程项目,需要在项目前期对关键技术适用性进行科学评价,以提供辅助决策依据。以东湖通道工程为研究对象,基于技术经济、生态工程、低碳交通多维视角,分析其关键适用技术要点,联合AHP法及云模型评价方法,构建绩效评价指标体系及评价模型,测评适用技术绩效等级,搜索识别关键不利绩效指标,弥补技术管理工作的不足。实证分析表明:湖底城市隧道空气净化系统关键技术绩效等级为中等,其不利绩效指标数居首,需紧密结合隧道工程稳定运营要求、充分调研技术可靠度、模拟技术对环境的影响、进行技术绩效评价,以降低不适用性风险。

The urban lake tunnel is a typical complex project,which need the scientific evaluation of the applicability of key technologies in the early stage of the project to provide supportive decision-making basis. This paper analyzed the key applicable technical points of East Lake channel project based on multidimensional perspectives of technological economy,ecological engineering and low-carbon transportation,and the performance evaluation index system was established. Then,an evaluation method combined AHP and cloud model was built to evaluate the applicable technology performance level of urban lake tunnel. By searching the key adverse performance indicators,it can make up for the shortage of relevant technical work. The empirical analysis shows that the key technology performance level of urban lake tunnel air purification system is medium,which adverse performance index is top. It is necessary to closely integrate the requirements of stable operation of tunnel engineering,thoroughly investigate the technical reliability,simulate the impact on the environment,and conduct technical performance evaluation to reduce the risk of non-applicability.
