Soil Characteristics and Its Behavior in the Lower Flood Plain of River Daya in Odisha, India

T. K. Lohani, K. P. Dash


The river bank of Daya in the S-E of the state of Odisha is presently mushrooming with constructions and infrastructural developments. Since the region is devoid of solid and hard rock basement, it has become a matter of concern for the technocrats and architects to provide suitable and stabilized foundations for those upcoming massive structures. The present study reflects the complex behavior of the soil parameters whose index and engineering properties have been determined strictly based on Indian Standard codes. The lithological variation of the land shows the entire region is spread by a thick blanket of clayey soil having high porosity with less permeability generating a swampy land throughout the year. But fortunately at a shallow to deep the stratum is defined by a compact, hard and impervious lateritic bed that gives ample support for a safe and stable foundation. Due to this, selection of foundation for construction purpose has become a challenging job. In the present research two nos. of boreholes were drilled up to 10m NGL, laboratory experiments were conducted and soil parameters were determined. From the various studies of soil it was found that clayey sand, sandy clay and thick blanket of clay pre-dominates the study area. Load bearing structures are completely unfavorable on such type of soil. Due to expansive nature of soil, deep foundation/pile foundation is suggested.
