Abstract
An investigation was conducted to develop two-dimensional 2D and three-dimensional 3D stability charts for slopes susceptible to translational failure. Translational slides usually result from thr presence of a heterogeneity located beneath the slope surface in the form of a strong material underlain by a material or an interface that mobilizes low shear strength. This strength usually results from sliding through preexisting failure surface along which residual shear strength is mobilized in soils or through geosynthetic interfaces of landfill liner systems. Such situations create relatively planar shear surfaces and predpmonantly translational slide movement.
An extensive parametric study was conducted to develop the required charts using a slope model that was designed to simulate field conditions with respect to configurations of sliding mass, and unit weight and shear strength of the involved materials. Slopes subjected to different conditions of pore-water pressure and seismic forces were also considered in the study. The study showed the special importance and difficulties of considering the end effects in the analyses of translational slope failures and suggested a method for quantifying and incorporating them.
The developed charts do not require iterative procedure in estimating the factor of safety. They are different from the few available ones dealing with translational failure mode. They are more comprehensive regarding the utilized sliding mass configurations, material unit weight and shear strength parameters, pore-water pressure, loading conditions, and methods of quantifying and incorporating he 3D effect.
The slope stability degrees of sensitivity to several parameters were also determined and interpreted. These parameters are the slope height, width and slope angle, the upper and lower materials friction angles and unit weights, inclination and depth of the weaker materials or interface beneath the slope toe, pore-water pressures represented by water table heights, and intensity of applied surcharge and seismic forces.
The presented charts will give the practicing geotechnical engineer a fast and reliable method to estimate the two and three-dimensional factors of safety for slopes susceptible to translational mode of failure and to back-calculate the mobilized shear strength of materials invloved in slope failures following such mode. Numerical examples are given to illustrate different uses of these charts.
