DetallesCálculo de pilotes con hélices (Ver video) Los pilotes con hélices utilizan las propiedades de los tornillos para crear un fuerte contraste en las acciones tanto de compresión como de tracción.Consisten en un fuste tubular cilíndrico de acero de alta resistencia, armado con tornillos helicoidales y con punta de perforación. La inserción en el terreno hasta…
DetallesEstabilidad 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…
DetallesSheet 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.…
DetallesLimit 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…
DetallesAbstract – Shallow foundations This article refers to the design of shallow foundations and highlights the normative requirements following the introduction of EC7-1. The calculation model used is in Appendix D of prEN 1997-1 2003 recognized as: the determination of the load limit of a foundation resting on cohesive soil as a short-term analysis. We…
