| 摘 要： | 苏州阳澄湖周围的沼积湖积平原存在一种性质较为特殊的淤泥质粘土,其亲水性粘土矿物含量和液塑限指标均较高,但在天然状态下虽具一定的胀缩性却未达到膨胀土的标准,可是经过扰动压实后,随着干密度的增大和含水量的减少却表现出较强的胀缩性,即转变为人工膨胀土1]。本文通过苏州阳澄湖东北方向某一级公路附近3个取土场土样的试验分析,探讨了此地区这种淤泥质粘土的特殊性,为以后的工程施工提供了科学依据。

| Abstract: | A sort of silty clay which has both high hydrophilic clay mineral contents and high liquid and plastic limits exists in the swampy and lacustrine plain in Yangcheng Lake area of Suzhou..Although it has certain swelling and shrinkage properties in the natural state,it doesn't belong to classical expansive soils.But while this soil is disturbed and compacted,with the dry density increasing and water content decreasing,its swelling and shringkage properties become very apparent.Hence the remolded clay can be called man-made expansive soil.Through analyzing the outcome of the experiments on the soil samples taken from the three earth-fetching areas on the northeast of Yangcheng Lake,from which the earth for the road base is collected,this paper discusses the special properties of the silty clay in this area and provides the scientific guidance for the future construction. |
