【Abstract】 This paper presents two kinds of influence function formulae due to either suddenly or harmonically acted tangential load uniformly distributed over a circular area on the surface of an elastic half-space. Using the method of influence function, formulae for determination of the tangential displacements of points outside and inside the bases of circular or rectangular foundations, as well as the average displacement of these bases are introduced. The results of this paper may also be used for determination of the parameters of the lumped analog of vibration of the circular or rectangular foundations.更多还原
