TL;DR: In this paper, the effects of interaction between shallow and deep foundations are not very well understood or studied, and the authors have performed a detailed parametric study using finite element techniques to better understand stress distributions and developed a simplified method to analyze this type of foundations.

Abstract: Growing urbanization is leading to more structures being constructed close to each other, resulting in substantial interaction between their foundations. Although the interaction between two shallow foundations and between piles in a pile group has been studied by several researchers, the effects of interaction between shallow and deep foundations are not very well understood or studied. Not much published literature is available for practicing engineers to analyze and design shallow and deep foundations that are constructed adjacent to each other. The second author of this paper was recently involved in a project in which a structure designed to be supported on drilled shafts was supposed to be constructed adjacent to another structure designed to be supported on a large mat foundation with high floor load. Although the authors have performed a detailed parametric study using finite-element techniques to better understand stress distributions and develop a simplified method to analyze this type o...

Abstract: The new Paradisus Coco Beach Resort in Rio Grande (PR) is located on an old swamp area which has been filled with relatively clean to silty sands. The swampy deposits consists of organic silts, peat and loose fine to medium sand and silty sand. The project requires the placement of 1.0 to 1.5 meters of additional fill together with the construction of light structures. The need for the fill will trigger the development of settlements in the underlaying weak ,and compressible stratum. Furthermore, the susceptibility of the loose sand to liquefaction during an earthquake was considered.

TL;DR: In this article, a hard layer of soil-cement was placed over the stone columns as load transferring platform so that the layer transferred a reduced stress to the soft soil and stone column composite foundation.

Abstract: Reinforcing the soft clay with stone columns is one of the most accepted techniques for improving the ground. Use of stone columns increases the bearing capacity and reduces the compressibility of soft clayey soil. However, due to the application of the vertical load, the stone columns bulge and hence settlement occurs. To reduce the bulging and vertical settlement, a hard layer of soil–cement was placed over the stone columns as load transferring platform so that the layer transferred a reduced stress to the soft soil and stone column composite foundation. A series of laboratory experiments was conducted on single and a group of stone columns with and without the soil–cement bed. The effects of the thickness of the soil–cement bed, length of the stone columns and spacing between the stone columns were discussed. It was observed that due to the application of soil–cement bed, the bulging and vertical settlement of the stone column reduced noticeably and load carrying capacity increased appreciably. All the experimental results were compared with the numerical results obtained from ABAQUS-3D and a good correlation between the results was obtained.

...(2) Twice the original value is used for piles based on recommendations by Bowles (1997). (3) The original formula includes a factor ‘C’. For the purpose of this text the value of ‘C=1.13’ is adapted. The original paper used the exponent 0.11 which is changed to its equivalent 1/9 in this paper. (4) The critical length should be calculated from the given equation in the last column by trial and error. (5) The Randolph (1981) formula is derived from a parametric finite element study. The above relationships hold for homogeneous, linearly elastic soils. These types of soils are very rare. Most soils show some increase in their modulus with depth. Some relationships are given for a soil modulus that increases linearly with depth. Randolph (1981) proposed the following relationship for the critical length of the piles in linearly varying soils (notations are modified):...
