Effect of Water Content on Apparent Cohesion of Soils from Landslide Sites

There are many empirical equations published for unsaturated fine-grained soils. However, there is only one equation established silty sand using the shear-box test and filter-paper-based suction test, but with range of 0 to 200 kPa. It reported that a significant discrepancy between predicted values results apparent cohesion within 100 kPa coarse-grained The purpose this research study effect water content on predict soils without much inconsistency. In research, soil samples from rainfall-induced landslide sites were obtained; laboratory tests such as soil-classification tests, consolidated undrained triaxial carried out. Test analyzed, findings presented. When increased 0% 30%, reduction 89% in average. A newly developed prediction model based low matric introduced paper compared models.
