An Experimental Study on Variation of Shear Strength for Layered Soils

Abstract

Compacted soils in embankments of dams, and roads, dikes, liners, etc. are commonly used in geotechnical engineering. Soil variability and uncertainty of a natural soil deposit and its properties are common challenges in geotechnical engineering design. The shear strength characteristics for different types of soil for different combinations of soils were used which are compacted in layered to form homogeneous and heterogeneous soils of thickness L, L/2, L/3 and 2L/3 i.e., 72mm, 36mm, 24mm and 48mm to form two and three layer system. It is observed that addition of layer of course grained soil with the fine grained soil leads to increase in the angle of friction and decrease in the cohesion.
