CALCULATION OF VARIATIONS AND SLOPE STABILITY
EL CALCULO DE VARIACIONES Y LA ESTABILIDAD DE TALUDES
The safety coefficient of a slope and the worst slip line are determined by applying variation calculations, avoiding the traditional method of trial and error by successive approximations. When the safety factor is expressed in terms of a function, the Euler equation enables a direct determination to be made of the worst of all slip curves which pass through two given points of the profile of the slope. The cross-sectional conditions facilitate determination of the two points mentioned so as to obtain the worst slip line among all the possible lines which fulfil certain conditions of regularity. In order to demonstrate the potential of the method, it is applied to janbu's method for the case of a wholly cohesive ground and of a slope of exponential profile. The results, obtained in non-dimensional form, are compared with Taylor charts for a slope of straight profile. /TRRL/
