Etude géologique et géotechnique de la voie ferrée Djelfa / laghouat, PK 62+ 000 au PK 82+ 000

Abstract

The establishment of railways requires a specific approach according to a set of standards proposed by the International Federation of Railways in order to achieve good performance in the Stability and Sustainability Plan. In this context we contributed to the geological and geotechnical study which consisted in conducting a series of field and laboratory experiments on samples collected to determine physical properties And the mechanical superstructure and infrastructure of the floor. In fact, these results are used to determine endurance prospects and classification platforms. This is necessary to design a structure. On the economic and technical level, the provision of better quality materials is necessary to achieve the ground and the treatment of unstable areas. According to the hydrological study, the surface water flow map and the map are based on the digital model of the terrain. We have produced a map that distributes areas of water stagnation that pose a danger to the railways. To avoid this dilemma, we have proposed a model with a focus on improving and protecting the sensitive components by replacing the soil with waterproof materials to ensure the best stability on the entire base and rail floor
