Ultimate Bearing Capacity Analysis of Square Footing on Two Layered Soil

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.
