A landslide occurred in the cut slope located in Chongqing west railway station, this slope belongs to a under-dip shale slope, which means that its bedding dip angle is larger than slope angle and it is comprised of soft rock. Some on-site investigations have been made to explore the deformation characteristics of this slope, the outcome suggested that sliding, buckling and toppling deformation existed at its different parts. To elucidate the complex failure mechanism exhibited by the under-dip slope under the long-term influence of gravity and material deterioration, the discrete element method has been employed in simulations. The simulated failure patterns have proven to be in strong agreement with the actual slope failure. This study suggests that sliding, buckling and toppling occur at different parts of the studied slope in sequence.

Se produjo un deslizamiento de tierra en la pendiente de corte ubicada en la estación de ferrocarril oeste de Chongqing. Ésta pendiente pertenece a una pendiente de lutita debajo de la inmersión, lo que significa que su ángulo de inmersión es mayor que el ángulo de inclinación y está compuesto de roca blanda. Se han realizado algunas investigaciones en el sitio para explorar las características de deformación de esta pendiente, el resultado sugirió que existía deformación por deslizamiento, pandeo y caída en sus diferentes partes. Para dilucidar el complejo mecanismo de falla exhibido por la pendiente de inmersión bajo la influencia a largo plazo de la gravedad y el deterioro del material, se ha empleado el método de elementos discretos en simulaciones. Los patrones de falla simulados han demostrado estar muy de acuerdo con la falla real de la pendiente. Este estudio sugiere que el deslizamiento, el pandeo y el vuelco ocurren en diferentes partes de la pendiente estudiada en secuencia.
