Reasons for Failure of Waterproofing System in Subway Stations with Complex Strata

With the rapid development of urban subway transportation networks, the waterproofing system of subway stations in complex strata plays a crucial role in ensuring the normal operation of underground stations. This paper analyzes the reasons for the failure of waterproofing systems in subway stations, focusing on issues such as self-waterproofing of concrete structures, waterproofing of detailed structures in subway stations, and failure of flexible waterproofing materials. Through case analysis and impact analysis, combined with construction characteristics, the paper summarizes the reasons for the failure of waterproofing systems in subway stations with complex strata and proposes preventive measures and repair methods.
