“…All the 5 th percentile values at different depths can be joined to form a 5 th percentile curve, and the process is repeated for the other percentile values. This procedure was adopted by Houlsby (2010). The meaning of these curves is that, if the statistical parameters correctly define the true uncertainty, one would expect that about 50% of measurements would fall between the 25 th and 75 th percentiles, and 90% of measurements would fall between the 5 th and 95 th .…”

“…Each of the individual measurements is within the expected range, but the trend is incorrect. Houlsby (2010) suggested that this scenario could be treated in a heuristic way, setting out a decision table based on where the measurements are, and whether or not they follow the expected trend, Table 1. Whilst this may have some value, it is possible to take the statistical approach further to understand the correlations as well as the individual values.…”

This paper presents some examples of design problems for offshore foundations, drawn from the jack-up industry and the wind turbine industry. The examples are chosen to illustrate some general points about foundation design, geotechnical engineering and its interaction with other disciplines. The first example is drawn from the assessment of the safety of installation of jack-up units (large mobile offshore drilling rigs). It illustrates how more rational approaches can be achieved through a deeper use of probabilistic methods in both the prediction of performance and the assessment of field observations. The second example also comes from jack-up practice, but has wider application too: it addresses the classical problem of the performance of foundations under combined loading, and how this can be understood in a simple theoretical and practical framework based on plasticity theory. The final example comes from the renewables sector, where the rapidly expanding offshore wind industry poses new foundation challenges for geotechnical engineers. Practical and economic foundation solutions are required if the UK is to meet its ambitious plans to exploit larger turbines in deeper waters. Both conventional (monopile) and novel solutions (suction caissons, screw piles) to the foundation problem are discussed. The paper also demonstrates how interactions with other disciplines can enrich geotechnical engineering, illustrated by specific practical examples from the Author's experience.

Te earlier bearing capacity estimation techniques were developed from both experimental investigations and analytical approaches, which led to semiempirical methods.…”

The bearing capacity of a square footing on an unstabilised and geogrid-stabilised granular layer over clay is estimated using finite element techniques in ABAQUS (a commercial finite element software). The model incorporates a range of soil parameters and layer thicknesses. The two-layered soil system in the model assumes a strong upper granular layer and a weak lower clay layer. The parametric results of the finite element analyses are used to develop design curves with dimensionless parameters in terms of linear gradient and the ratio of the undrained shear strength of clay to the effective vertical stress of the granular layer. The design curves are compared with the published results in the literature and found to be promising. The developed design curves are applied to estimate the minimum thickness of the granular layer and are compared with other existing methods. This application illustrates the simplicity of the proposed technique and reveals that the proposed approach yields a reasonable prediction for the bearing capacity when compared with other established methods.
