Bearing capacity of model footings on sand

Abstract

Soil mechanics engineering is one of most important aspects of civil engineering involving the study of soil , its behaviour and application as an engineering material.good soil engineering embodies the use of the best practices in exploration,testing ,design and construction control,in addition to the basic idealized theories. with increasing load on soil due to construction of multi storeyed buildings there is a need to construct footing by conducting a test of their model in laboratory on the soil over which the foundation is to be laid. Sand is one of the soils over which foundations are laid ,so it is necessary to conduct experiments by placing different model footings over sand and find out their ultimate bearing capacity and based on these values ,it can be incorporated on to the field and foundations can be laid. Square footings of different sizes are taken and model testing of these footings are conducted and the ultimate bearing capacity of different footings are found and on the basis of these values foundations are laid on sandy soils .these values can also be compared with theoretical analysis of Terzaghi and Meyerhof ‘s to check out the difference in values of ultimate bearing capacity between a theoretical and practical analysis.
