| 摘 要： | 路基稳定性实质上包括竖向变形和侧向变形，过大的侧向变形会引起附加沉降，同时对边坡的稳定性有一定的影响。通过对碎石垫层处治、强夯碎石垫层处治等不同地基处治方式的断面沉降特性进行对比分析，结合侧向位移观测数据．发现因侧向位移产生的沉降量约占总沉降量的20％。

| Abstract: | The roadbed stability includes vertical distortion and lateral deformation. The excessive lateral deformation may cause the additional settlement and influence the slope stability. The crosssection settlements of different disposal types like crushed stone cushion diposal and strong tamper crushed stone disposal are compared and analyzed, then it is found that the settlement caused by lateral displacement occupies about 20% based on experiment data. |
