Pham_Ch5_Figure5_10_SAFE

SAFE: Figure 5_7 to 5_12 show the locations of the critical slip surfaces obtain by various methods. The results from the SVSLOPE-SAFE software as well as the M-P method, the Bishop's Simplified method, and the Enhanced (i.e: Stress-Based) method. Various conditions were analyzed with different soil properties used in each use. The symbol S34-1030 means that the case has a submerged slope. Poisson's ratio is 0.48 and the soil cohension and the angle of the internal friction are 10 kPa and 30?, respectively.

This example is used to verify the SVSLOPE-SAFE for a simple homogeneous 2:1 slope with a groundwater table passing through the toe of the slope. The soil is assumed to behave as a linear elastic material.

The analysis methods used for this study are:
Ordinary,
Bishop,
Janbu Simplified,
Spencer,
M-P (Interslice Force Function - Half-sine), and
GLE (Interslice Force Function - Half-sine).

The search method for the critical slip surface is "Grid and Tangent". The grid and tangent methodology is one of the most common methods of determining the critical circular slip surface. In this methodology, the trial slip surfaces are specified by a grid of centers and a set of lines to which the circular slip surface must be tangent. The critical slip surface is considered to be circular.
