摘要：

The dynamic finite element model of slab track on the subgrade or bridge was established based on the theory of finite element and ANSYS software to calculate the concrete strain rate of slab track in different load cases. The results indicate that the concrete strain rate of slab track increases with the improvement of train speed and it is bigger than the slab track on the bridge. The concrete strain rate of slab track under multiple moving loads is larger than that under single moving load. The concrete strain rate of slab track is from 10-4 to 10-2 s-1, and the strain rate is in dynamic performance category of concrete.
