Resumo:
Many problems of geotechnical engineering can be solved by superposition of the fundamental singular solutions to the governing differential equations. In the dissertation, the mechanical behavior of a flexible footing is investigated, in terms of stress and settlement distributions, considered some basic fundamental solutions published in literature. These solutions refer to the stress and displacement fields in an isotropic, homogeneous, linearly elastic half-space generated by a vertical force applied on the surface (Boussinesq´s problem (1885)), a horizontal force on the surface (Cerruti´s problem (1882)), a force within the half- space (Mindlin (1936)) or within a stratum of finite thickness (Burmister´s problem (1945)). For the case of horizontal stratified soil deposits there are very few solutions available, in spite the common occurrence of this kind of soils in nature. One of such solutions has been proposed by Hisada (1995), which permits the response of a stratified half-space to dynamic or static forces, applied at any given point of the elastic medium, to be numerically computed. In the mathematical development, the application of the Green`s theorem allows the superposition of fundamental solutions to be more easily done by transforming area integrals into line integrals along the boundaries that define the geometry of either a single footing or a group formed by any number of shallow foundations. Some examples are herein presented in order to indicate the potential use of this approach to geotechnical engineering problems, in general, but with special emphasis to those of the foundation engineering.
