| 摘 要： | 强夯法是一种设备简单、施工方便、经济易行的地基处理方法.它对增强地基密实度、消除土层湿陷性、降低土层压缩性和提高地基承载力效果显著.针对兰州中川机场场道工程,通过原位测试试验,分析比较了试夯前后的湿陷性黄土物理力学特性、湿陷性、比贯入阻力等特性,证明了强夯处理湿陷性黄土效果显著.

| Abstract: | The dynamic compaction method is a kind of method for foundation treatment.It is not only simple and convenient but also economical and feasible.It can improve the degree of density of foundation,delete the collapsible feature of soil layers,lower compressibility of soil layers and increase loading capability of foundation.The change of physical-mechanical properties of loess before and after dynamic consolidation and collapsible properties as well as specific penetration resistance are studied by means of in-situ tests in Lanzhou Zhongchuan Airport.The obvious effect of adopting dynamic compaction method is manifested. |
