The validity of saint-venant's principle in sandy soils

In soil mechanics, to give you quick results, to be useful and reliable due togeotechnical problems often are referred to the theory of elasticity. One of theexample that implementation of the theory of elasticity to engineering problems isSaint-Venant?s principle. In this study, model experiments can be made verticalstress analysis, stress distribution in the ground floor and the Saint-Venant principlein the validity of the sandy soil was investigated. In experiments for measuring straingauge (stamp strain) were used. Loading applied as a uniform circular load basis. Inaddition, the results are compared with theoretical results.
