摘要
安徽“312国道”大量使用“合肥膨胀土”作为路堤填料。本文介绍了在此类膨胀土中加入不同量石灰后其主要性质的变化。试验结果发现,当加入6％的石灰时,可以很好地改善其工程性质。通过对微结构和成分的分析,确认膨胀土性质的改善是由于土与石灰间发生复杂物理化学作用,促使其微结构发生改变的结果。
The 'hefei swelling clay'is Widely used as em-bankment fills in the construction of 312--road inAnhui Provine. It has high to moderate swelling po-tential of this Clay will be largely reduced and itsengineering properties greatly improved if 6% limeadded. Itis is recongnized that there are compli-cated actions between the soil and lime, resulting inthe formarion of a new microstructure-aggregate-skeleton structure,by which the engincering prop-e ties of the swelling clay are improvel.
