The invention provides a gas-steam combined cycle waste heat boiler fault monitoring method and system, and belongs to the field of waste heat boiler fault monitoring. The method comprises the steps that a plurality of to-be-monitored heating surfaces of the waste heat boiler are determined, and a smoke end total measuring point and a working medium end total measuring point of the waste heat boiler are obtained; a smoke end monitoring strategy is selected according to the smoke end total measuring point, and the smoke end of the waste heat boiler is monitored based on the selected monitoring strategy; a working medium end monitoring strategy is selected according to the working medium end total measuring point, and the working medium end of the waste heat boiler is monitored based on the selected monitoring strategy; a smoke end monitoring result is obtained, and the fault state of the smoke end of the waste heat boiler is judged according to the smoke end monitoring result; acquiring a working medium end mo
