利用车辆-轨道耦合动力学理论所编制的程序，计算弹性轨枕有碴轨道与普通轨枕有碴轨道在相同工况下的动力响应。
By running the program based on vehicle-rail coupling dynamics, compute the dynamic response of elastic sleeper ballasted rail and common sleeper ballasted rail under same working condition.
研究结果：在同样荷载条件下，板层之间无紧密连接的无碴轨道的板层拉应力要大于板层有紧密连接结构的拉应力；
Research results: Under the same load condition, the tensile stress of ballastless track slabs without close connected is bigger than that of slabs with close linkage structure.
