摘要间歇性列车荷载与降雨湿化耦合作用下有砟轨道路基的翻浆冒泥机制及动力特性尚不明确。开展间歇荷载–湿化耦合作用下有砟轨道路基翻浆冒泥模型试验，试验结果表明：循环荷载作用对体积含水率与孔隙水压力增长具有促进作用，且促进作用随土体干密度增加而减弱。累积变形和颗粒迁移主要发生在LS1～LS3阶段，LS2阶段因试样处于较高饱和度与较低密实度状态变化最为显著。后续各加载阶段因土体密实度较高仅产生少量累积变形，颗粒迁移现象不明显，间歇期(IS4～IS7阶段)出现小幅回弹。试验结束时，道砟孔隙污染物指数(VCI)为27%，与需要进行铁路维修的临界值40%较为接近，需引起重视。

Abstract：The mud pumping mechanism and dynamic characteristics of ballasted track subgrade under intermittent train load and rainfall wetting coupling are still unclear. A mud pumping model test in ballasted track subgrade under intermittent load-wetting coupling was conducted. The experimental results indicate that the cyclic loading has a promoting effect on the increase of volumetric water content and pore water pressure，and the promoting effect weakens with the increase of dry density. The accumulated deformation and particle migration mainly occur in the LS1-LS3 stages，and the changes are most significant in the LS2 stage because of the high saturation and low density of the soils. In the subsequent loading stages，only a small amount of accumulated deformation occurs due to the high density of the soils，and the phenomenon of particle migration is not obvious. A small resilience occurs during the intermittent period(IS4-IS7 stage). At the end of the experiment，the ballast void contaminant index(VCI) is 27%，which is close to the critical value of 40% for railway maintenance and needs to pay attention.

Key words： subgrade engineering mud pumping intermittent load model test accumulated deformation particle migration pore water pressure
