摘要

土体的微结构对土的工程力学特性具有决定性影响，对上海原状淤泥质黏土在不同固结压力下进行了固结试验，同时对相应荷载作用下的土样进行SEM试验，进而对每级荷载下土样水平切面和垂直切面上的土团粒（包括团粒的形状、平均表面面积及团粒的定向性分布）进行统计对比分析；另外，通过压汞试验对土体的孔隙进行定量分析。二者相互结合，从而揭示土体发生变形的宏观机制及土体在受力过程中具有逐渐破损、产生各向异性的特征。

Abstract

The soil microstructure has a significant influence on engineering mechanical behavior. SEM tests are dealt with Shanghai intact mucky clay in different consolidated pressures during one dimensional consolidation test. And particles (including aggregate shape

mean surface area and orientation distribution) both from horizontal cut plane and vertical cut plane of the specimen are analysed and compared. In addition

the pore of soil has been analysed by means of mercury intrusion porosimetry test. Through these analyses

it is concluded that the soil represents character of damage gradually and material anisotropy during loading condition from tests above.
