ETUDE D’UN OUVRAGE D’ART SUR OUED EL MALEH A LA RN 108 AU PK 56+180

Abstract

The work presented in the present report consist of the study of an engineering work situated in the National Road 108 which is still in progress He project joins within the framework of the operation of the halving of the RN 108 on 20 KM connecting AIN TEMOUCHENT with HAMMAM BOUHDJAR , as which the realization of this work serves as a natural obstacle (OUED EL MALEH) on one hand and on the other hand allows to serve the second way recently created . The structure consist of three spans of 27M of twelve beams spaced by 0,9 M in prestressed concrete with a slab of 25 cm . A detailed study has been elaborated on the structural element of this bridge in particular (studies of the deck, beams and supports) the work carried out using finite element methods using the SAP2000 numerical code . The results of the modeling have led to dimensioned and verify the various criteria of stability and security of this infrastructure.
