摘　　要：基于锦承线K39+780 m处路基冻胀的实际情况,分析了导致土体产生严重冻害的原因,提出了在模型中埋设横向碎石桩的方法,模型试验结果表明,在箱体中铺设一定量的碎石桩,会起到阻隔地下水上升的作用,增强了路基的整体稳定性。Based on actual subgrade frost damage of Jin-Cheng railway line at K39 ＋ 780 m section, the paper analyzes soil frost damage causes, and puts forward the method of embedding horizontal gravel pile in the model. The model test results show that paving certain amount of gravel pile in the box may prevent underground water hoisting and increase the overall subgrade stability.
