摘　　要：以天津滨海新区软土为研究对象,通过研究其固化后的无侧限抗压强度和微结构特征,分析其固化机理.添加剂的加入使得其孔隙变小,结构变得比较致密,固化后土体强度得到了一定提高.此外,对土的宏观力学性质与微结构特征之间的关系进行了探讨.The soft soil in Tianjin Binhai New Area was taken as investigated subject and the consolidation mechanism was analyzed according to the study of unconfined compressive strength and microstructure features of its solidified soil sample.The use of addition in sample causes the pore become smaller and the structure become denser,that can improve the strength of solidified soil to some extent.Moreover,the intrinsic relationship of this kind of soft soil between macro-mechanical characters and microstructure fe...
