Ultimate Bearing Capacity Analysis of Square Footing on Two Layered Soil

Ashish Kumar Bera, Subir Sasmal

Abstract


In this present paper a series of model footing tests has been conducted on layered soil. In this investigation top layer kept as granular soil such as sand and bottom layer clay. From the experimental results it is found that with increase in depth of top layer thickness (d) the ultimate bearing capacity of footing increases. The optimum value of depth of top layer thickness depends on relative density of sand. From the present experimental results a non linear power model has been developed to predict the ultimate bearing capacity of square footing on layered soil.
