摘要
为全面了解公路山岭隧道衬砌结构补漏技术的最新研究进展,文章通过对既有公路山岭隧道的调查和统计,结合大量的文献资料,从防排水设计、材料和施工等方面分析了渗漏现象的本质,明确了隧道抗渗防漏的薄弱部位和保证补漏效果的关键环节;从衬砌混凝土、施工缝、变形缝和活裂缝等方面,介绍了当前国内外补漏技术的最新研究成果(包括补漏涂材、构造补漏和施工工艺等);并探讨了当前隧道补漏技术存在的问题和发展的新趋势。
In order to fully understand the advances in the leak-stopping technology for highway mountain tunnels, this paper analyzes the seepage mechanism of tunnels regarding design, materials, and construction based on extensive literature, investigation, and statistics of existing highway mountain tunnels opened to traffic in the last 5 years. The weaknesses of anti-seepage and impermeability and the key steps of leaking stoppage are also discussed. The latest research findings on leak-stopping technology, including coating materials, constructional measures, and construction technology both at home and abroad, are introduced in terms of lining concrete, construction joints, deformation joints, and live cracks. Additionally, the problems and trends of current leak-stopping technology are discussed.
