Soil Reinforcement Methods for Environmental Protection of Slope Failure Against Landslides

Abstract

Slopes are not stable due to the variations of slope gradient combined with the driving forces including the groundwater action, producing shear stresses in the slopes, which are contradicted by the soil shear strength. The slopes instability may cause the displacement of the mass of soil downstream recognised as landslide. Consequently, landslides are one of the most significant catastrophic phenomena observed on the earth surface. This phenomenon can be considered as a major concern on the social and economic point of view and for the quality of life of a local population, including also the environmental impact on the ground water level, blockage of rivers, road destruction, forests and ecosystems destruction, etc. Therefore, soil reinforcement has become one of the best forms of embankment protection against slopes failure. This work used soil reinforcement methods by using retaining structures, slope design with low gradient and vegetation cover to stabilize the embankment. The usage of the shear strength reduction technique was carried out to evaluate the stability of embankment slope. This process has tendency to reduce shear strength as rarer as failure is produced. This study is achieved along with pseudo-static and static methodologies. Varied parameters influence on the stability of slopes are revealed by accomplishment of many studies. To end, the Static method findings are acceded to comparison with the ones found by Pseudo-Static method. The results showed that the stability of reinforced slopes was reached and the slope can resist against landslides.
