Session: Shallow Foundations

ABSTRACT: The aim of study is to establish fairly reliable forecast of consolidation parameters for alluvial deposits and finally total settlement at a specified time by passing statistically not acceptable tests with reference to time and cost both. New approach is evolved for quick analysis and to assess sensitivity of structure at a site for settlement. The derived parameters and approach is quick and economical. Empirical model is prepared to predict the settlement of shallow foundations incorporating soil index and plasticity characteristics. The model incorporates the computation of over consolidation ratio, time rate settlement, magnitude of settlement and differential settlement of foundations. The model will be useful for foundation design incorporating the differential settlement of foundations. Key Words Alluvial Deposits, Empirical model, Foundation Settlement, Shallow foundations, Soil Consolidation, Soil Properties.
