Abstract: | |
The correlation of different properties of soil play an important role in many practices for soil and foundation engineering. It may not be possible to conduct large number of time consuming shear and consolidation tests, where, the structure is built on a thick clayey deposit. Again, there are also difficulties to recover undisturbed soil samples from very stiff to hard clayey layer as well as very soft clay layer. But the strength of these layers are essential to be known for design purpose. Under such conditions, correlations are important to estimate the engineering properties of soil. Kolkata being one of the largest metropolises in India and mostly founded on alluvial deposit, has been taken into consideration for our study. In this study, laboratory test results and borehole logs from many parts of Kolkata and Rajarhat-Newtown area, provided by various private companies have been considered. The available collected data of boreholes from Kolkata and New Town area gave all the parameters required to make the equations and their graphical representation. Since the process of consolidation test, shear strength test, triaxial test or unconfined compression strength test etc. are time consuming, the correlation of different properties of soil play an important role for design purposes. |
