通过对我国第一条铁路客运专线———秦沈客运专线路堑段基床表层的动态测试,得到了厚度分别为40cm与60cm的基床表层在不同车速下的动应力与加速度值,分析了它们在基床表层横向与深度方向的分布规律及其与速度的关系。
Through the dynamic test on the bed surface of the first section of Qinling-Shenyang Passenger Dedicated Line in China, the dynamic stress and acceleration values of the bed surface under the different vehicle speeds of 40cm and 60cm are obtained respectively. They are distributed in the horizontal and the depth direction of the bed surface and their relationship with the velocity.
