Abstract: The high-speed train makes strict demands on the long-term performance of the track-subgrade. The key scientific point of research on the performance of high-speed railway subgrade is the mechanical and hydraulic properties of the subgrade under the coupling of dynamic cycles, dry-wet cycles, and temperature cycles. Much further research work should be done for the maintenance of existing high-speed railways and the new construction of high-speed railways.

高铁路基近期研究

随着高速铁路的快速发展，高铁路基的研究成为一大热点。目前大量的研究工作集中在高铁路基动力响应、工后沉降和长期服役性能。这些工作促进了对高铁路基一般规律的了解，但距准确评价路基在百年服役过程中经受干湿循环、温度变化与动荷载耦合作用下服役性能的改变尚远。本文总结了高铁路基近期的研究成果，并提出了未来的研究方向。
