The invention discloses a method for monotonically calibrating the pressure of a large coke oven carbonization chamber, and mainly discloses a method for dividing a coking period into a plurality of sections according to the change trend of the pressure in the whole coking process of raw coke oven gas in the large coke oven carbonization chamber through a measurement and adjustment method. A fixed carbonization chamber pressure monotonic control value is set in each section, so that the raw gas in the carbonization chamber can be smoothly discharged out of the carbonization chamber, reaches a gas collecting pipe, then reaches a gas suction pipe and finally reaches a gas purification system, and the whole standard operation process of stable operation of raw gas pressure control is achieved; the invention aims to develop a pressure monotonous calibration method for a carbonization chamber, and aims to balance that when the pressure of the carbonization chamber at the initial stage of coal charging is too high,
