Estabilidad de taludes: Por talud se entiende una porción de vertiente natural cuyo perfil original ha sido modificado con intervenciones artificiales relevantes con respecto a la estabilidad. Por derrumbe se entiende una situación de inestabilidad que concierne vertientes naturales y comprende considerables espacios de terreno. Introducción al análisis de estabilidad Para resolver un problema de…
Sheet Pile Walls – Overview In order to have a more efficient usage of construction areas in congested urban areas a vertical development of buildings becomes necessary. Currently we more often face situations where urban buildings need as many parking spaces, so, due to lack of space, that requires the development of several underground floors.…
Limit equilibrium methods for slope stability analysis do not, in general, satisfy the overall equilibrium conditions; they must make assumptions regarding the inclination and location of the interslice forces. An alternative slope analysis based on the discrete element method is presented to avoid these drawbacks. A slope in the present model is treated as comprised…
