摘要
水下隧道设计基准期一般为100年,在长期运营过程中会遇到结构耐久性不足而导致的各种病害,危及隧道内行车安全,降低水下隧道使用寿命。随着工程全寿命周期的概念深入人心,以健康监测系统为基础进行水下隧道智能监测逐渐得到重视,成为隧道安全运营的重要课题。文章针对水下隧道健康监测技术收集了已有相关研究资料,对隧道健康监测基本概念和常用技术进行了总结,分析了水下隧道健康监测的重点和难点。结合国内外典型水下隧道健康监测系统应用实例及部分实测结果,系统的论述了水下隧道健康监测系统的实施情况和实施效果。以此为基础,对未来的发展趋势进行了展望。
The underwater tunnel design reference period is generally 100 years,in the long run there will be insufficient durability of the structure caused by various diseases,endangering traffic safety in the tunnel,reducing the service life of the tunnel under the water. With the development of engineering life cycle concept,the health monitoring system based on intelligent monitoring of underwater tunnel has been paid attention,which has become an important issue for the safe operation of the tunnel. This paper summarizes the basic concepts and techniques of tunnel health monitoring,and analyzes the key points and difficulties of underwater tunnel health monitoring. Based on the typical examples of tunnel health monitoring system at home and abroad,the implementation of the health monitoring system for underwater tunnel were systematically discussed. On this basis,the future development trend is prospected.
