饱和软粘土固结、蠕变变形和应力松弛规律

Law of Consolidation Creep Strain and Stress Relaxation in Saturated Soft Clay

本文通过室内试验着重研究饱和软粘土在排水和不排水条件下简单加载和重复加载时的固结、蠕变规律,在排水条件下土体静止侧压力系数K_0(t)的历时降低规律,以及土体的剪应力松弛规律和松弛过程中侧压力系数历时增长的规律,并且介绍了以上这些规律的工程应用价值。

This paper is emphasized on studying the law of consolidation and creep strain when simple load or repeated load is applied under the drained or undrained condition on the basis of indoor test, the law of decreasing of coefficient of earth pressure at rest K_O(t)under drained state and the law of soil shear stress relaxation, as well as the law of increasing of lateral pressure coefficient during relaxation. Application of those laws in practical engineering is also introduced in this paper.
