Abstract

The paper combines the Boundary Strip Method (BSM) previously presented by Michael, Avrashi and Rosenhouse (1994), with domain decompositionAvrashi, Michael and Rosenhouse (1995), for analysis of the settlement of foundations embedded in a continuous pit. The soil beneath the foundation is either more rigid or more flexible than the foundation material. The effect of pavement rigidity and its thickness on its deflection is investigated. We distinguish between two sub-domains - one of which is the relatively rigid (say, a concrete slab) and the other is the half space which consists of soil. The foundation which is located in a pit having the shape of a long strip, loads the lower interface between its body and the ground. During the parameter analysis, the pavement strip is of varying width and thickness. The foundation is separated vertically from the ground by a thin slit The geometry of the problem, which is two-dimensional is defined by straight contour segments, for which the BSM coefficients matrix is built. The construction of the matrix is based on analytical integrations developed previously by Michael, Avrashi and Rosenhouse (1995). Numerical results of the analysis summarize the paper.
