| 摘 要： | 以南水北调中线一期工程总干渠河北邯郸段所取膨胀土样为例,通过大量室内试验,得到了膨胀土在击实状态下,当含水率较小时,干密度随含水率的增大而增大,而当干密度增大到某一值后,含水率的继续增加反而使干密度减小.研究结果表明,含水率和干密度呈二次抛物曲线关系的特征.

| Abstract: | Based on lots of laboratory tests,taking the sample of the expansive soil in the Handan section of Hebei province in the first-stage of project in the middle route of South to North Water Diversion,obtain the expansive soil under the compaction condition,when the water content is low,the dry density increase with the increase of the water content,When dry density reach a certain value,the continual increase of the water content cause the dry density decrease.The results of the study show that water content ... |
