Effect of L/D Ratio of UCC Specimen on Shear Strength of Clay Soil

Abstract

The role of Geotechnical engineering application in land reclamation, construction of highway, railway and canal embankments require a very large quantity of soil of desirable properties. It is often difficult to obtain good quality soil for the above applications from the nearby quarries. In such a situation, the locally available problematic soils (having low shear strength high compressibility and swelling nature) after stabilizing the same with the addition of admixtures such asuse of sand, lime, cement etc. for the improvement of problematic soils is costly because of their high demand in other civil engineering applications. To overcome the difficulties experienced with problematic soils in geotechnical applications on one side and safe disposal of solid wastes on the other side, an attempt is made in this study to explore the possibilities of utilizing to improve the engineering behaviour of problematic soils. In this study an attempt is made to know the index properties, compaction and unconfined compressive strength, may be used to improve the strength properties in four different types of problematic soil which have high swelling and high compressible nature. It can be concluded the as the L/D ratio decreases the unconfined compressive strength increases.
