Abstract

Subway drainage system can be an important part to ensure the daily operation of subway stations. Through investigation and theoretical analysis, it is determined that the weak part of subway drainage system is water pump, and its reliability requirements are analyzed through reliability block diagram. After allocating the demand index, the fault tree model is established. The minimum cut set of fault tree is found and calculated, and the reliability index of subway drainage system is put forward after determining the importance of each event. The results show that the failure rate of subway drainage system is 0.0004/ h, and the most effective way to improve the reliability of the system is to improve the reliability of water pump motor.
