Abstract: The saturation and consolidation status of soil samples is very important in the triaxial test of saturated loess. The vacuum saturation is a common effective way to saturate samples in the test. It is very difficult to saturate the remoulded loess samples by vacuum saturation which may destroy the structure of remoulded loess. So the remoulded loess samples have to be saturated on the triaxial apparatus. A number of saturation tests and consolidation tests are carried on the unsaturated triaxial apparatus of GDS for remoulded loess at Lanzhou. A tee-joint is installed on the triaxial apparetus to cut down the time of saturation test and consolidation test. Also it is a better way to simulate the soils in natural state through up and down to saturate and consolidate. This work contributes to the saturation and consolidation of silty clay in the triaxial test.
