Introduction the expansive soil shows obvious volumetric changes under changing moisture conditions. these volumetric deformations usually result in differential movements of shallow foundations resting on it. consequently, structural damages could happen if no special measures would have been taken during the design process. this article illustrates the possibility to predict such movements us...

Experimental data from loading tests of model circular footings on soft normally consolidated clay are presented. The experiments were carried out on a drum centrifuge at a radial acceleration level equivalent to 100 times Earth’s gravity, ensuring conditions of stress similitude between the model and the prototype scale. The aim of the experiments was to compare the undrained response of diffe...

Offshore wind turbines play a key part in the renewable energy strategy in the UK and Europe as well as in other parts of the world (for example, China). The majority of current developments, certainly in UK waters, have taken place in relatively shallow water and close to shore. This limits the scale of the engineering to relatively simple structures, such as those using monopile foundations, ...

In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...

Shallow foundations in granular soils are designed such that the settlements are within tolerable limits. Schmertmann’s (1970) method is one of the most rational methods for computing settlements of footings in granular soils, and is commonly used world-wide. The method relies on a strain influence factor that varies with depth. Schmertmann et al. (1978) proposed separate strain influence facto...
