Table 2 shows the interface shear strength parameters including interface cohesion and friction coefficient at different temperatures and initial water contents. The interface cohesion presented a similar variation trend with the peak shear stress, while the effect of test temperature and initial water con...
The physical and mechanical parameters of the in-situ expansive soil at the slope slip zone taken from the field borehole are shown in Table 1. Among them, the cohesive force and internal friction angle of the expansive soil were obtained from the quick shear test. In order to further clari...
