    Abstract:

    The operation of large track maintenance machinery mainly includes tamping operation and grinding operation, which is an important operation mode to maintain the good geometric state of the line. In order to formulate a reasonable tamping and grinding operation plan and ensure the safe operation of the line, the annual tamping and grinding operation plan preparation model is developed to optimize the average annual geometric irregularity and the field operation capacity as constraints, and the improved enumeration method is used to solve the model. The model has been applied to the Beijing-Shanghai Railway for verification. The results show that the operation plan of large track maintenance machinery developed by the model can improve the improvement rate of track geometric state, reduce the average value of annual geometric irregularities, and provide a reference for the planning of on-site tamping and grinding operations.
