Abstract:
In order to investigate the characteristics of loess on south bank of crossing the Yellow River Project in the Middle Route of South-to-North Water Diversion Project, and the slope stability of loess under different working conditions to provide design support for the subsequent channel excavation scheme, the strength tests of unsaturated loess were conducted in the study area. The experimental tests included the tests of physical properties of loess, the CU triaxial tests of saturated loess, the tests of soil-water characteristic curve, and the shear tests of unsaturated loess. The results showed that the loess in the study area is clay with low liquid limit, large quantity of silt, low water-holding capacity, and a suction internal friction angle of =7.58°.
