Abstract
Estudios y pruebas sobre la resistencia en macizos rocosos demuestran que la envolvente a los círculos de Mohr es una curva
plana cuya tangente cambia de posición en función del intervalo
de esfuerzos. En la presente investigación se estudia la estabilidad
en macizos rocosos mediante los criterios de rotura no lineales de
Úcar y de Hoek y Brown, y se analizan y compararan resultados en
taludes de macizos rocosos considerando rotura plana cuya superficie potencial de rotura se genera únicamente por deslizamiento.
En base a los aspectos señalados, se ha minimizado el factor de seguridad, y por ende la inclinación más crítica del plano potencial de
deslizamiento, teniendo en cuenta la sobrecarga, la inclinación de la
corona del talud, el efecto sísmico y las presiones intersticiales
Studies on the strength of rock masses have revealed that the envelope of the Mohr circles forms a flat curve, with the position of the tangent changing based on the stress range. This research aims to investigate the stability of rock masses using two nonlinear failure criteria: Úcar’s criterion and Hoek-Brown’s criterion. The analysis focuses on comparing and evaluating results in rock slopes, specifically considering planar failure, where the potential failure surface is solely due to sliding. Taking into account these aspects, the safety factor has been minimized, thereby identifying the critical inclination of the potential sliding plane. This analysis considers various factors, such as overburden, upper slope inclination, seismic effects, and interstitial pressures.
