| 摘 要： | 以贵阳龙洞堡国际机场试验段工程为例对岩溶洼地填筑体变形及稳定性进行数值模拟研究。研究结果表明:强夯对岩溶洼地地基土处理具有较好的效果，能有效降低填筑体的沉降量及边坡位移量；填筑体沉降量随着填筑体厚度减小而减小。

| Abstract: | Taking the engineering in the test section of Longdongbao International Airport in Guiyang as the example，the fill deformation and stability of karst depression is studied through numerical simulation.The result shows that dynamic compaction is good way to treat the foundation soil in karst depression and could reduce the fill settlement and the slope displacement effectively，while the fill settlement is decreased with the decreased fill thickness. |

| Keywords: | karst depression dynamic compaction deformation and stability numerical simulation |
