Abstract：
Summarizes sources and control standards of the main hazardous gases in the cavern during operation of the hydropower station underground powerhouses, and briefly describes the ventilation rate calculation methods of the battery rooms and the oil tank rooms. Analyses the minimum outdoor air rate for underground powerhouses of hydropower stations from the aspects of removing hazardous gases and meeting the requirements of indoor air quality, which provides references for the ventilation system design of hydropower station underground powerhouses.
