Slope stability assessment for block-in-matrix composite-materials by the tortuous surface method

This thesis deals with the general problem of slope stability analysis in bimsoils/bimrocks and tortuous failure surfaces in slopes. The problem was handled by means of developing an application software named pyBIMstab that is capable of randomly generating bimsoil/bimrock structures inside a slope...

El problema se resolvió mediante el desarrollo de un software de aplicación llamado pyBIMstab que puede generar aleatoriamente estructuras de bimsoils/bimrocks dentro de un talud, definir automáticamente las superficies que pasan rodeando los bloques aplicando un algoritmo de búsqueda de trayectorias llamado A* y evaluar el factor de seguridad de dichas superficies mediante el método de equilibrio límite. pyBIMstab se usó para realizar miles de análisis para diferentes condiciones y se obtuvieron algunas conclusiones a partir de eso. Finalmente, se propone una metodología para realizar correctamente el análisis de estabilidad de taludes compuestos por bimsoils/bimrocks mediante un enfoque estocástico para lidiar con las incertidumbres sobre la dispersión del factor de seguridad para bimsoils/bimrocks con la misma proporción de bloques.Maestríaapplication/pdfspaUniversidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Ingeniería CivilEscuela de Ingeniería CivilMontoya Araque, Exneyder Andres (2019) Slope stability assessment for block-in-matrix composite-materials by the tortuous surface method.
