| 摘 要： | The disruption, yield and water content change of a remolded unsaturated loess is studied during the course of shear tests with controlled net mean stress equaling constant. Two types of density's triaxial drained shear tests with controlled net mean stress and suction equaling constants are conducted. The test results show that the disruption stress increases with suction. A new method to identify the field stress under triaxial drained shear tests with controlled net mean stress equaling constants is suggested, and the shape of loading-collapse yield curve are similar in q-s plane and in p-s plane. The soil-water characteristic curve is dependent on deviatoric stress, and the soil-water characteristic curve including water content, suction, net mean stress and deviatoric stress is proposed.

The test results show that the disruption stress increases with suction. A new method to identify the field stress under triaxial drained shear tests with controlled net mean stress equaling constants is suggested, and the shape of loading-collapse yield curve are similar in q-s plane and in p-s plane. The soil-water characteristic curve is dependent on deviatoric stress, and the soil-water characteristic curve including water content, suction, net mean stress and deviatoric stress is proposed. |
