Analyse de stabilité par modélisation numérique d’une section du tunnel T2 de Kherrata. Wilaya de Bejaïa

Abstract

Taking account of the landslide problem of the Kherrata tunnel dug in wet terrain is a very important element in the stability study of the structure. This is the framework for the work presented in this brief.The various components of the tunnel support system were estimated from the BIENIAWSKI classification system. The behaviour of the work is determined by a numerical calculation in finite elements «MEF», using the Plaxis-2D-Tunnel calculation code which bases on the two-dimensional modelling of the study section and finite by the detection of displacements. To validate the effectiveness of previous recommendations and ensure tunnel stability.
