ENGINEERING PROPERTIES OF A SPECIAL SOFT SOIL ENCOUNTERED DURING HIGHWAY CONSTRUCTION IN XUYI CITY, JIANGSU PROVINCE

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.
