中文摘要：

为了解决公路隧道设施众多及信息异构分散等特点对公路隧道养护决策带来的困难,本文在对公路隧道养护特点分析的基础上,进行了从隧道全生命周期信息出发,利用大数据分析对隧道养护评估和优化进行了研究。文章围绕全生命周期养护评估方法和优化决策,描述了全生命周期信息评估决策的基本原理和实现路径,并根据评估结果进行了有约束条件下的养护策略选择。最后,文章对该方法的创新点和应用效果进行了总结,并指出了未来隧道养护评估的发展趋势。

英文摘要：

In order to solve the the problems caused by diversifed information in the highway tunnel,this article analyzes the characteristics of highway tunnel and uses big data analysis and assessment of BIM technology to study the tunnel maintenance and optimization. Based on the evaluation of the whole life cycle maintenance and optimization decision method,the article describes the basic principle of whole life cycle information evaluation decision and implementation path,and makes strategic choices according to the evaluation results. Finally,innovation points and application effects of this method are summarized,and the future development trend of the tunnel maintenance evaluation is pointed out.
