结合高速铁路客运专线一段面进行了现场动态测试,探讨了不同行车速度下路基的动力响应问题,并分析了动应力的分布规律,为进一步研究基床在动荷载作用下的响应规律积累了资料和参考依据。
The dynamic response of subgrade under different driving speeds was discussed with the dynamic test of the first section of high-speed railway passenger dedicated line. The dynamic stress distribution was analyzed and the data were accumulated to further study the response of subgrade under dynamic load And reference basis.
