The 2014 Hans Cloos lecture: Engineering Geology—some feedback regarding the practice of a scientific and technical discipline

Autor: Roger Cojean

Publikováno v: Bulletin of Engineering Geology and the Environment
Bulletin of Engineering Geology and the Environment, Springer Verlag, 2015, 74 (4), pp.1087-1103

This Hans Cloos lecture paper develops general reflections inspired by Ian McHarg’s (1969) book, “Design with Nature” and concerning engineering geology. Three case studies are illustrated: landslides in reservoirs, gallery excavation in a shie

Impact d’une galerie étanche peu profonde sur l’écoulement d’une nappe

Autor: Michel Deveughèle, Pierre Zokimila, Roger Cojean

Publikováno v: Bulletin of Engineering Geology and the Environment. 69:143-152

On etudie la modification de la surface piezometrique d’une nappe, initialement en ecoulement uniforme, liee a la presence d’un ouvrage lineaire d’axe horizontal perpendiculaire a la direction de l’ecoulement. Pour une nappe captive, on propo

Prise en compte des discontinuités dans l’élaboration d’un modèle mécanique de massif rocheux. Application au creusement de l’écluse à bateaux du barrage des Trois Gorges (Chine)

Autor: Jean-Alain Fleurisson, Roger Cojean

Publikováno v: Revue Française de Géotechnique. :47-56

This paper is related to the stability analysis and evaluation of the long term deformability of the permanent shiplock rock slopes at the Three Gorges Dam site. On the one hand, a detailed stability analysis was performed using the DEGRES software (
