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 ...

Two methods for incorporating the effects of negative pore water pressures into the slope stability analysis are proposed in this paper. the derivation of equations for the factor of safety with respect to force and moment equilibriums are presented. Several ...

The side slopes of a railway embankment in central British Columbia, constructed with local lacustrine silt, on relatively flat ground, began to fail several years after construction. Shallow instability ultimately developed on both sides of the embankment ...

The equations of statical equilibrium and the failure criterion for the soil are insufficient to render a slope stability analysis determinate. Generally, the problem is resolved by making assumptions regarding the interslice forces. Calculated safety factors ...

An independent analysis must be performed in order to obain the pore water pressures for a slope stability analysis. These pore water pressure conditions may result from eth effects of construction or they may result from the natural groundwater condition. ...

Evaluation of limit equilibrium methods with emphasis on factor of safety calculation, slip surface, interslice force function.

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 ...

<p>Evaluation of different limit equilibrium methods for slope stability analysis and factor of safety comparison.</p>

The concept of pore pressure parameters has been found convenient to visualize the pore pressure response of saturated soils for various applied stress changes. This paper derives pore pressure parameters that can be utilized in determining the pore pressure ...

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 ...
