摘要
目前在膨胀土中掺加定量水泥是改良膨胀土的主要处理方法之一，通过综合南阳膨胀土试验段工艺试验成果中的检测数据，分析弱、中膨胀改性土拌合后随即压实和放置14d后压实两种情况下，土料压实干密度、自由膨胀率、无荷载膨胀率与时间的关系，总结在膨胀土经过水泥改性、压实以后的自由膨胀率和无荷载膨胀率中长期改性效果，以供研究探讨。
At present, expansive soil mixed with the quantitative cement is one of the major approach of improving expansive soil, this paper though the results of the test data in Nan yang expansive soil test craft test,analysis the relationship between the dry density of compacted soil, the free expansion, the expansion without toad and time in the condition of the mixed weak expansive soil compacted and placed 14 days. , summary the medium and long term effects of the free expansion and non-load expansion rate in the expansive soil that modified by cement and compacted, for research to explore.
