The invention relates to the technical field of engineering, and discloses a high-speed train operation safety and vibration comfort coupling evaluation method under wind shear, which comprises the following steps: calculating a train safety index overturning coefficient, pantograph displacement and a vehicle dynamic envelope and vibration comfort index based on environment information and vehicle information obtained by a target train in a high-speed running state; when the safety index overturning coefficient of the train is larger than a first preset threshold value, early warning is conducted; when the pantograph displacement and the vehicle dynamic envelope obtained by the monitoring system are greater than the pantograph displacement threshold value determined by calculation, the vehicle dynamic envelope threshold value performs early warning; when the vibration comfort degree index is greater than a second preset threshold value, performing early warning; obtaining a CWC curve based on overturning safety and vibration comfort through numerical solution, and controlling the vehicle according to the CWC curve based on overturning safety and vibration comfort under wind shear after early warning; according to the method, the problem that the vibration comfort and the safety risk cannot be judged at the same time through an existing comfort judgment method is solved.
