Abstract:

In this study the effect of gravity on the strength of cohesionless soils is investigated. In particular, the effect of gravity on the bearing capacity of footings on cohesionless soils is considered. Coulombs equation for shearing strength and Terzaghis bearing capacity theory are analyzed to determine theoretically the influence of gravity. Penetrometer experiments were performed on six soil models under gravity forces of 0, 0.168, 1, and 2 times that of the earth using an Air Force KC-135 jet aircraft. The experimental results show that the ultimate bearing capacity of cohesionless soils is directly proportional to the gravity field. This is the result predicted on the basis of Terzaghis bearing capacity theory. Author
