To determine the mode of slope failures is very difficult especially when using the conventional slope stability method which applies the linear type of strength variation with respect to effective stress and suction. These studies conducted to fulfil the real failure mechanism of slope failure which acquired the analysis of shear strength behaviour incorporatecurve-linear relative to effective stress and non-linear relative to suction. Three undisturbed samples were collected at Precinct 9, Putrajaya at different depth to determine the multistage triaxial drained test with unsoaked, soaked for 7 days and soaked for 14 days sample.Finding shows that from the test, there are a slightly reduction in shear strength between all the samples. For unsoaked sample, the shear strength was 280, soaked for 7 days was 250 and soaked for 14 days was 220. The shear strength parameters obtain from the results will used in slope stability analysis in order to define the Factor of Safety for the slope failure.
