Abstract：
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.
