根据高速列车的荷载特点，着重分析研究了高速轨道的动力响应及轮轨间的相互作用。建立了计算模型，进行了大量计算，并根据计算结果分析了轨道部件及轨道几何不平顺对轨道动力响应的影响，进而对高速轨道结构模式与几何标准提出了建议
According to the load characteristics of high-speed trains, the dynamic response of high-speed rail and the interaction between wheel-rail are analyzed emphatically. The calculation model is established and a large number of calculations are carried out. Based on the calculation results, the influence of track parts and orbital irregularities on the dynamic response of the track is analyzed, and the suggestions on the mode and geometric standard of the high-speed track are put forward
