This paper presents the results of numerical investigations on the deformation behaviour of a tunnel face reinforced by longitudinal pipes. The three dimensional finite difference calculations are based on series of reduced-scale centrifuge model tests (Al Hallak, 1999). Numerical analyses are developed and carried out with particular emphasis on the validation ...
This article compares and analyses the behaviour of three test embankments. The soil foundation consisted of
normally consolidated clay overlain by a thick sand surface layer. The embankments were rapidly constructed until failure,
which occurred after approximately 50 days. Two of the embankments were reinforced, one including prefabricated
vertical drains (...
