摘要
对上海软粘土进行的大量固结不排水试验中发现,在不同的围压下土体表现出来的力学性质是有差别的。我们将常规三轴试验和平面应变试验中得到的应力—应变关系曲线和应力路径曲线进行了归一化处理,结果发现土体的固结压力对土体的力学性质有很大的影响。
In the consolidated undrained tests of Shanghai soft clay, we discover that the mechanics characters of soil are different in different consolidation pressure. We normalize the stress-strain curves and stress path curves in triaxial tests and plane strain tests and discover that the consolidation pressure has prodigious influence to the mechanics characters of soil.
