Abstract
Tunnel engineering plays a crucial role in modern transportation infrastructure construction, yet groundwater leakage severely impacts the structural safety and service life of tunnels. To address this challenge, this study focuses on the application of high-performance waterproofing materials, aiming to explore efficient waterproofing solutions suitable for complex geological conditions. By systematically reviewing existing waterproofing technologies both domestically and internationally, and considering the practical requirements of tunnel projects, polyurethane-based materials, bentonite-based materials, and advanced polymer composites were selected as key research subjects. Combining laboratory simulation experiments with field applications, an in-depth analysis was conducted on the mechanical properties, durability, and construction techniques of these materials. The results indicate that the novel polymer composite materials exhibit superior bonding strength and anti-seepage capability, maintaining stable performance under various water pressures, with significantly improved construction convenience compared to traditional materials. Innovatively, a multi-layer composite structure-based waterproofing system was proposed, effectively resolving the issue of easy damage to traditional single-layer waterproof membranes and enhancing overall waterproofing efficiency. This research not only provides a reliable basis for selecting waterproofing materials in tunnel engineering but also offers new insights and technical support for waterproof design in similar underground projects, contributing significantly to the advancement of tunnel engineering technology in China.
