Environmental Protection Measures Against Landslides Impacts Caused by Slope Instability

Abstract

Each slope is affected by 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. The current study makes the usage of the shear strength reduction technique to evaluate the stability of slopes. This process has tendency to reduce shear strength as rarer as failure is produced. This study is achieved along with pseudostatic 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.
