| 摘要： | It is important to properly design the waterproofing and drainage system of a tunnel to preserve its durability but also the safety and the durability of its internal spaces and technological systems. Yet this objective cannot be reached with the use of a single geomembrane alone. Rather, meeting this objective requires a waterproofing system, where the geomembrane is one important component. The choice and the correct design of an appropriate waterproofing system is the basis of a good and safe project. Another important component in combination with the PVC-P geomembrane is the protection/drainage layer made by a geocomposite that must be compatible and properly work in combination with the PVC-P geomembrane. To ensure a proper draining-protection effect to a tunnel waterproofed with a PVC geomembrane, it is recommended to install a drainage geocomposite between the geomembrane and the gunite layer. |
