Réhabilitation d'un pont bipoutre implanté à Tamanrasset

Abstract

The aim of this thesis is to study the problematic concerning the bridge linking the wilaya of Tamanrasset and In Salah and crossing Oued outel, which has experienced degradation of concrete slab following the frequent overflows of water at the time of floods. . In order to find the adequate solutions for a better functioning of the bridge and the satisfaction of the technical standards and codes of practice, it was decided in consultation with the SAPTA and the TP Department engineers to increase the length of the bridge by the addition of two additional bays to the ends of the existing bridge. The work was developed using the Robot V2009 calculation software for determining the transverse and longitudinal distribution of the loads and mobile overloads on the composite beams and slab. On the basis of the results obtained from the modeling of the deck, the dimensions and the necessary checks of the elements of the deck as well as the pile and the abutment were carried out
