摘要
通过用改装的应力 -应变控制式三轴仪 ,对等应力比条件下的非饱和原状黄土进行了“分级浸水”,同时测试了试样在初始、加压固结和浸水湿陷几个状态下孔隙气压力和孔隙水压力的变化过程。初步分析了非饱和原状黄土湿陷变形特性以及湿陷过程中的孔隙水压力。
The stage slaking test for unsaturated intact loess are performed under the condition of constant stress ratio by means of refitted triaxial apparatus controlled by stress and strain. The variation process of pore air pressure and pore water pressure of samples at several states, such as primitive consolidation, as well as collapse state, are tested, respectively. The collapse deformation characteristics of unsaturated intact loess, the variation regularity of pore air pressure and pore water pressure, as well as matrix suction during it′s collapse process are analyzed primarily.
