Design Chart of a footing located on a Crest of the Unsaturated Soil slopes

A parametric study points out the effect of various influential parameters on the stability of the unsaturated clayey and alluvial soil slopes using finite element computer programs of GEOSLOPE. The rainfall intensity and duration is considered as one of the studied parameters, three intensity values are selected (10, 24 and 50) mm/day (with different duration 10, 20, 30, 40, 50 and 60) day. Phreatic line level is the second parameter studied, at 2, 4, and 6m from surface. In addition to that, footing width is studied as the third parameter. Consequently, three different widths are selected (1, 2, and 3m). Slope angle is also selected as the fourth parameters; four different angles are selected (31, 45, 63 and 81) degree. As a result, a chart for routine design is obtained.
