RESUMO:

A structure foundation, whether a highway or a building, requires geotechnical conditions of stable soils, meaning that the planned investment is without risk. In case if that is non-existent, the geotechnical engineer should to do a needed analysis,  in order to solve possible risks. The presence of soft soil in any terrain, whether from surface or even in sub horizontal layers, naturally makes necessary a stability calculation, usually it involves computational analysis. This study contributes to a better knowledge of the landfill technique over reinforced soft soils with jet grout column, preceded for load transfer platform with geosynthetic, so as his evolutionary behavior in consolidation process resulting time. The study case place is detailed and the made geotechnical investigation will be present. As the used parameters are presented in landfill construction project over soft soil of the work project of duplication of BR-101/RN highway, the called northeast corridor, his history and geotechnical baseline. The methodology adopted shall be demonstrated to made road structural reinforcement with jet grouting technique, being described how the estimated parameters are used in modeling treated soil. The application of the proposed methodology is presented using as geotechnical scenario the soil characteristics of the Vale do Curimataú area with this model utilization, it is intended to compare numerically the displacement datas that was measured in field, this area has a failure before this intervention study. Were observed a failure conditions  and excessive deformations and to stabilize it, was applied the jet grouting technique. The building behavior  was analyzed in pre-construction period. To a successful performance of landfill over soft soil, it makes necessary to monitor in all the construction stages, installing control instruments to follow the soft layer and massif performance, movement soil evolution, the horizontal displacements, and prevent of some future problems that could negatively affect the landfill stability.
