摘要
合肥新桥国际机场地基膨胀土采用了石灰改良处理,本文通过对改良前后膨胀土的工程性质的研究,利用扫描电镜分析,从微结构的角度来解释了石灰改良膨胀土的机理。
Lime treatment of expansive soils was applied to the foundation of Hefei Xinqiao International Airport. This paper studied the engineering properties of expansive soils before and after their improvement, applied scanning electron microscope (SEM) to analysis and interpreted the mechanism of lime-treatment of the soils.
