摘要
相比于加载过程 ,卸载过程抗剪强度的变化要复杂得多 ,强度指标也表现出明显的不确定性 .笔者就土体卸载后的不同膨胀程度分析了各种情况下的 τ～σ关系 。
The variation of shear strength of unloading clay is m ore complex than that of loading clay,the clearly undetermined property of inten sity indices is also displayed.The relation of τ σ in varying condition i s analyzed on the basis of different degree of expansion,and the quantified rela tion between stress relaxation and hold up hours is discussed in this paper.
