富水隧道衬砌结构安全分级评价及系统开发

Safety Grading Evaluation and System Development of Lining Structure of Water-rich Tunnels

随着隧道工程迅速发展,衬砌结构安全评价逐渐成为行业的重点和难点问题。基于此,文章考虑水环境对衬砌结构安全的影响,建立了适用于富水隧道的衬砌结构安全评价指标,并基于这一安全指标评价体系及相应的评价标准,结合两种不同的评价算法——系统可靠度理论和指标权重法进行系统开发,最后以此为基础对西南地区某隧道工程进行结构安全等级评价。

With the rapid development of tunnel engineering,the safety evaluation of lining structure has gradually become the key and difficult problem in the industry.Based on this, this paper considers the influence of water environment on the safety of lining structure, and establishes the safety evaluation index of lining structure suitable for water-rich tunnels. Based on this safety index evaluation system and corresponding evaluation criteria, combined with two different evaluation algorithms-system reliability theory and index weight method, the system is developed, and the structural safety grade of a tunnel project in southwest China is evaluated on this basis.
