| 摘 要： | 在非饱和土固结理论的基础上,分析了降雨入渗条件下全填筑和全开挖膨胀土路基变形的特征,获取了浸水后膨胀土路基内塑性区的发展过程,得出了膨胀土路基一般发生浅层滑动的结论,这种滑动与通常饱和土的边坡失稳的原因是不同的。

| Abstract: | Based on the consolidation theory of unsaturated soils, the numerical simulation of deformation of expansive soil roadbed under the condition of rain infiltration is made. The development of plastic zone is studied. The results show that the shallow slide of expansive roadbed generally happens; and its instability cause is different from ones of common saturated soils. |

| Keywords: | expansive soil roadbed shallow slide |
