The invention relates to a method for cyclically and iteratively adjusting a train working diagram and a speed curve under temporary speed limit. The method comprises the following steps: step 1, configuring a rail transit line road network model for optimizing the train working diagram and the speed curve, characteristic parameters of a motor train unit, parameters of an initial working diagram, basic parameters of train operation and standard parameters of train operation time; step 2, configuring basic data parameters of the temporary speed limit scene; 3, a train working diagram adjusting model under the temporary speed limiting condition is established; 4, establishing a speed curve adjusting model under the temporary speed limiting condition; and step 5, obtaining an adjusted train working diagram and a speed curve under temporary speed limit. By means of train speed curve calculation based on the technical parameters, the road network parameters and the temporary speed limit parameters of the motor train unit, the speed curve of the train in the temporary speed limit disturbance scene can be obtained more finely, and accurate evaluation is provided for the feasibility of the adjusted working diagram.
