Statistical Analysis of Equipment Faults in Subway Tunnel Ventilation System and Allocation of RAM Indicators
By investigating the fault data of the tunnel ventilation system in subway stations,analyzing the weak links in equipment operation and maintenance,the types and causes of key equipment faults in the tunnel ventilation system,as well as the number and proportion of faults in each equipment type,were obtained.Taking into account the equipment failure rate and quantity,combined with the number of equipment failures and mean time to repair(MTTR),mean time between failure(MTBR)of key equipment in the tunnel air system is calculated.The RAM index can be used as a reference for peers.
