In this study, 11 types of rocks were measured by using the tilt test to investigate the effect of water saturation on the basic friction angle. The basic friction angle displays a reduction trend with decreasing water saturation, because the loss of surface moisture will reduce the suction effect. In addition, the basic friction angle is much smaller at a low temperature, because the created ice film promotes the shear slide of blocks. However, the tilt test should not be used at a low temperature, because the adhesive ice film on the sample surface could prevent the slide activation of cylindrical samples. Moreover, the effect of freeze-thaw treatment was also investigated. With increasing freeze-thaw cycles, the surface roughness increases while the basic friction angle decreases, because the bulges are more easily crushed under normal stress after freeze-thaw damage. It is suggested that the direct shear test method under a low normal stress should be adopted to determine the basic friction angle at the low temperature and freeze-thaw condition. This study has provided a better understanding of the changes of basic friction angle and a good choice of suitable measurement method at different temperature conditions.
