TL;DR: The torsional response of rigid foundations embedded in a non-homogeneous elastic soil with a weathered crust is investigated in this article, where the authors use an integral equation method based on displacement and traction Green's functions of the weathered nonhomogeneous medium.
Abstract: The torsional response of rigid foundations embedded in a non-homogeneous elastic soil with a weathered crust is investigated The shear modulus of the weathered crust is assumed to decrease linearly with depth and that of the underlying non-homogeneous soil increases linearly with depth The problems related to both rigid circular and cylindrical foundations are examined by using an integral equation method based on displacement and traction Green's functions of the weathered non-homogeneous medium Numerical solutions for torsional stiffness of rigid circular foundations are presented for different depths of embedment, gradients of shear modulus profile and depths of weathered crust A closed form solution based on a simplified stress field in the soil is also developed to evaluate the torsional stiffness of a rigid cylindrical foundation The torsional stiffness derived by using the approximate solution is compared with the rigorous solution based on exact Green's functions L'article examine la resist

TL;DR: In this paper, the undrained response of massive caisson foundations to combined horizontal, vertical and moment loading is investigated through a series of three-dimensional finite element analyses, and the ultimate limit states are presented by failure envelopes in normalized form.
Abstract: The undrained response of massive caisson foundations to combined horizontal, vertical and moment loading is investigated through a series of three-dimensional finite element analyses. The ultimate limit states are presented by failure envelopes in normalized form. The effects of embedment ratio and vertical load on the bearing capacity are investigated in detail. Closed-form expressions are proposed for (a) the yield surface in M-Q-N space, and (b) the lateral capacity under pure horizontal and moment loading. Finally, the use of an associated flow rule to define the plastic deformation of the caisson at near failure conditions is parametrically examined. The results of the analysis could serve as a basis for a macro-element approach.
