针对内蒙古清水河县工业开发园区的湿陷性黄土，开展了石灰粉煤灰改良黄土性能的压缩试验、湿陷性试验，并利用扫描电镜（SEM）进行了微观形貌观察，试验结果表明由于黄土、石灰、粉煤灰之间产生的化学反应，使黄土的压缩性降低、湿陷性消除、颗粒间的孔隙得以填充密实。本文为内蒙古清水河县工业开发园区湿陷性黄土地基处理方面提供一定的试验依据和施工方面的参考。

In view of collapsible loess in industrial development park of Qingshuihe County , Inner Mongolia Autonomous Region , Compression test and collapse test was carried out on the basis of loess performance modified by the lime and fly ash , meanwhile scanning electron microscope on the microtopography observation was used .As a result of the chemical reaction among the mixture of loss , lime and ash , the experimental results show that the mechanical performance improved , reducing the compressibility and eliminating the loess collapsibility of loess and intergranular pore getting compactly filled .The paper provides some test basis and construction reference for the collapsible loess foundation treatment in Inner Mongolia Qingshuihe County industrial development park .
