Abstract
The classical theory of isotropic elasiticity has been extensively used for estimating stresses developed in loaded soil mass, because of its simplicity. Natural soils and rocks, however, exibit essentially anisotropic nature. The first author, therefore, has derived basic anisotropic stress formulae in which stress distribution is controlled by just a single parameter of Young’s modulus ratio, n. Recently, artificial earth reinforcing members are inserted horizontally into the weak soils. This brings the foundation more anisotropic than the original and yields a higher horizontal rigidity. Thus the authors suppose to apply his solutions to this kind of problem. In this note, the stresses generated due to strip, triangular and embankment loading are obtained. The pressure bulbs are drawn to illustrate the load spreading capacity of anisotropic foundation. For engineer’s help, influence chart of vertical stresses due to embankment loading is prepared in a style of Osterburg’s for various values of n.
