experimental and numerical study of soil slopes at varying water content under dynamic loading condition

This paper presents both experimental and numerical study on a slope made up of c-ϕ soil. the effect of different reinforcements such as geotextile and geogrid are also studied in both cases. small shaking table tests are conducted on the model slope to evaluate the different parameters like acceleration amplifications and horizontal deformation at different levels of the slope. in addition to the variation of the c-ϕ nature of the soil, the variation of water content is also done for the model soil slope. the effect of variation of frequency level, base shaking and a number of reinforcement layers are also studied. using plaxis, numerical models are developed for both unreinforced and reinforced soil slope made up of c-ϕ soil. comparison of the results as obtained from the experimental study is done with those of the numerical models. results presented either in tabular form or graphically and from the results acceptability of the models is also discussed.
