SOILS REINFORCED WITH GEOSSYTHETICS: CONSTRUCTION WORKS OF BRIDGE AND VIADUES

Abstract

This work presents the use of soil retention techniques in landfills reinforced with geosynthetics in bridges and viaducts, with the objective of carrying out the feasibility analysis and application of the method, carrying out the survey of works carried out in Brazil and verifying the mechanical properties acting. It is concluded that the use of geosynthetics of high strength, high modulus and low creep, combined with energy compaction results in structures that are not deformable, that meet the requirements of aesthetic appearance and functionality, as well as safety to collapse in these works, as an alternative of great constructive flexibility and fast execution, making it relatively low cost compared to traditional construction methods.
