Soil Characterisation of an Artificial Island Accounting for Heterogeneity
The heterogeneous nature of soils and other geo-materials results in uncertainty in design and so it is important to incorporate this heterogeneity in analyses of geo-structure performance. However, before analysing the geo-structure itself, it is first necessary to statistically characterise the si...
