| 摘 要： | 盱眙地区软土成因复杂,矿物成分特殊,本文通过对其矿物成分、化学成分、颗粒分析、物理指标、膨胀性、压缩性等试验研究,对该软土的工程性质取得一些认识。结果认为该类软土中粘土矿物含量高、亲水性强,填土液塑限高、有机质含量高;在含水量高时碾压成饼状,含水量低时坚硬难以破碎,不能直接做路基填料,采用常规的掺灰处理效果不理想,是一种特殊性软土。

| Abstract: | The soft soil in Xuyi area has a very complicated origin and very special mineral compositions . The engineering geological property of this soft soil has been examined with the experimental tests including mineral compositions, chemical compositions, particle analysis, physical properties, expansive properties and compressibility in this paper. It's concluded that the soft soil with high clay content, better hydrophilicity, high liquid-plastic limit and high organic content. It cann't be filled for highway foundation directly. It's easy to be caky rolled in high water content and hard to be broken in little water content. So the result is not remarkable mingled with lime traditionally. It's a specific soft soil. |
