Ultimate Bearing Capacity of Purely Cohensive Null Gravity Soil on a Circular Foundation

In relation to the plastic flow of purely cohesive null gravity soil under the action of a circular foundation, the author assumes a stress field which satisfies basically allowable equilibrium and a velocity field which satisfies completely allowable motion; and solves the analytical solution of ultimate bearing capacity of that foundation by applying the principle of virtual power. This is a concise method with result in higher accuracy, as compared with that of numerical integration computation. It may serve as a reference to engineering design.
