... widely used to determine the factor of safety of a slope: the limit equilibrium method (LEM) and the shear strength reduction technique (SSRT). The LEM and the SSRT can generate distinct slip surfaces and consequently, distinct factors of safety from one another. The limit equilibrium method defines...

Field investigations strongly suggest the ongoing movement takes place along a basal slip surface, formed by a tectonized clay rich interbed, with mobilized friction angle close to residual. The influence of reservoir level increase on the slope displacement and mobilized...

... direction, and the key problem is the determination of whole potential sliding direction, which depends on the distribution of maximum anti-sliding shear forces on the potential slip surface. At the end of this paper, two classical examples of 3D slope are used to verify this method. The calculation results...

ABSTRACT: In this paper, combining the Geographic Information System (GIS) spatial analysis function with an improved Hovland''s 3D slope stability analysis model, a new GIS based 3D deterministic model is developed. Assumed the initial slip as ellipsoid, the 3D critical slip surface in the 3D...

..., it is necessary to consider several factors which are important in interpreting the test results. The samples were cut as shown in Fig. 11-A to constrain failure to two dimensions and slip was found to occur as represented by the surfaces ABCD, ABE, and CDF. These slip surfaces are shown as planes; however...
