Etude géologique et géotechnique du site d’un ouvrage d’art au niveau du barrage de Tabellout (PK 30+181 et PK 31+419) Wilaya de Jijel

Abstract

As part of the realization of the future dam of Tabellout, it was decided to build an overpass 1200 m length that will be to replace and final deflection of a section of the national road 77 will be immersed the future water dam of Tabellout. The purpose of this work is to verify the feasibility of the foundations in order to provide alternatives to the service of the DTP. Variables influence our choices are the lithological nature of the site, the geometry of the proposed foundations (sheets and diameters) and the practicality of achieving these foundations. The study contains two main complementary parts, geological and geotechnical investigations. A calculation of bearing capacity of bored piles with an empirical stimate of settlement will be a guide for DTP engineers in order to make appropriate decisions regarding this project
