A new three-dimensional (3D) slope stability analysis method is developed based on two-directional moment equilibrium. This method calculates not only the safety factor but also the possible direction of sliding for semispherical and composite failure surfaces. ...

Locating the critical cross-section and critical failure surface is the first step in the analysis of the static and seismic stability of landfill slopes. Locating the critical crosssection is usually accomplished by analyzing two-dimensional cross-sections ...

The landslide is occurring in rocks of the Franciscan Complex. In the area of the roadway it moves on the order of 1.5 to 3.0m/yr. Two inclinometers were installed in the slide to determine the depth to the failure plane(s). One of the inclinometers is located ...

Some of the methods of slices satisfying moment equilibrium derived for circular slip surfaces have been extended to accommodate noncircular (or composite) type slip surfaces. A question arises regarding the point about which moment equilibrium should be taken ...

A comprehensive study is presented to compare the factors of safety calculated by the Ordinary, Bishop's Simplified, Janbu's Simplified, Janbu's Generalized, Spencer and Morgenstern - Price methods. Results are presented in terms of stability coefficients ...

The paper compares six methods of slices commonly used for slope stability analysis. The factor of safety equations are written in the same form, recognizing wheter moment and (or) force equilibrium is explicitly satisfied. The normal force equation is of ...
