Based on the vehicle-track coupling dynamics, by means of finite element method, the vehicle-double-block ballastless track-subgrade vertically coupled model is established to research the dynamic properties of double-block ballastless track with unequal sleeper spacings under the excitation of either long wave irregularity or short wave irregularity. The results indicate that the difference between the sleeper spacing and the standard sleeper spacing of the double-block track within the range of 70mm will not effectively affect the vehicle operation. The unequal sleeper spacing has a certain influence on the vertical displacement and acceleration of vehicle, rail and wheel rail force, but its influence on the force properties of track structure and vehicle operation stability can be ignored.
