摘要：

The fast marching method (FMM) is a fast, accurate and stable travel time calculation method. It not only has fast calculation speed, good flexibility, but also has unconditional stability for any complex velocity field. Conventional travel time calculations are basically based on horizontal surface, which limits the application of methods in undulating surface areas such as mountains and hills. Based on the FMM, a calculation method for calculating the seismic wave travel time of the undulating surface of the undulating surface under complex geological conditions is proposed. The calculation results of the theoretical model show that the method is feasible for the travel time calculation under complex geological conditions.
