The applicability of the dynamic programming method to two-dimensional slope stability analyses is studied. The critical slip surface is defined as the slip surface that yields the minimum value of an optimal function. The only assumption regarding the shape ...

This paper presents a synthesis of mechanisms related to structure development of surficial heavy clay soils. These clay soils develop specific structural features due to wet/dry cycles and desiccation cracking they undergo during soil "ripening". There is ...

This paper reviews the development of finite element slope stability analyses and proposes that such a method can form a practical procedure for solving slope stability problems. Several slope stability methods have been proposed that make use of the finite ...

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.

The calculation of the lateral earth force using the limit equilibrium method of slices is an indeterminate problem. An assumption regarding the direction or the magnitude of certain forces, or the position of the line of thrust can be used to render the problem ...
