摘要：The use of rigid inclusions for soil bearing capacity and/or settlement control offers an efficient and economical alternative to the traditional pile foundations. The general approach towards analyzing a slab or a raft foundation on a rigid inclusion system is through the use of unit cell models constructed in programs which incorporate either the finite element or finite difference method. This type of model offers information regarding the interaction of the rigid inclusion with the surrounding soil and with the transfer layer. However, the effect of the inclusions on the global behavior of the slab or raft foundation cannot be anticipated in this manner. As such, three dimensional finite element models are necessary in order to study aspects such as the influence of foundation rigidity and the type and distribution of foundation loading on the bending moments and shear forces that develop in the raft or slab. In this article the results of an analysis of a raft foundation on a rigid inclusion reinforced soil, modelled in the finite element software, Plaxis 3D, are presented and discussed.
