Biot's theory of consolidation is implemented, by means of finite elements, in the solution of field consolidation problems. The method allows for simultaeous changes in geometry, loading and material properties during and after construction, and enables the influence of the stiffness of embankments and dams on their foundation pore pressures to be assessed. This is accomplished for two highway embankments and the calculated results are compared with field measurements. The validity of centrifugal modelling and the load transfer within dams with soft cores are also discussed. La théorie de la consolidation de Biot est étudiée aumoyen des éléments finis, pour la solution de problèmes de conslidation in situ. La méthode permet des changements simultanés de la géométrie, un chargement et des propriéstés des matériaux pendant et après contstructgion, et permet de tenir compte de l'influence de la rigidité des remblais et des barrages sur leurs fondation, la presssin interstitielle doit être évaluée. Ceci a été effectué pour deux remblais de route à grand trafic et les résultats des calculs sont comparés avec des measures in situ. La valdité du modèle cnetrifuge et la diffusion des charges dans les barrages à noyaux mous, sont aussi discutées.
Summary
Vertical and near vertical joints can have an important effect on tunnelling operations in rock. This paper describes an inclined drilling programme to study jointing along nearly 5 km of tunnel within the Kielder Water Scheme. Drilling problems are discussed, logging methods are described and the results are given. It is concluded that inclined drilling can have an important role in tunnel site investigations.
