Abstract The crack and leakage in concrete structure of subway stations is a difficult problem and need to urgently resolve in the near future. This paper presented adding polypropylene fiber to concrete, and the volume content of polypropylene fiber is determined by limit state design. This method was used in one subway station of Shanghai Rail Transit Line 7. The experimental results indicate that polypropylene fiber can improve the anticrack and water waterproof proof performance of concrete structures, satisfy the design requirements of subway station.
