The present invention discloses a gate adjusting and controlling method suitable for a series channel downstream emergency water interruption condition, and relates to the adjusting and controlling field. The method comprises the steps of constructing a water power simulation model of a to-be-monitored channel engineering; adopting a three-point water level control method to real-timely adjust a most downstream check gate where an emergency event occurs and the gate closing rate of all last-level check gates of the most downstream check gate until the inlet flow rate and the outlet flow rate of a channel pool to which any one check gate belongs are balanced, and stopping closing the check gate of the channel pool; calculating the real-time water storage quantity of the channel pool to which the check valve belongs according to the real-time flow rate of the check gate, utilizing the real-time water storage quantity at the current moment to adjust the flow rate of the check gate at thenext moment until the real-time water storage quantity of the channel pool is equal to the target water storage amount of the channel pool, thereby adjusting and controlling the gate of the channel where the emergency event occurs. The gate adjusting and controlling method of the present invention reduces the maximum damming height in front of the gate, reduces an overflowing risk, at the same time, can adjust the water level after the emergency event is ended, and prevents the water level after the stabilization from being too high.
