ABSTRACT
In geotechnical and geological engineering, we frequently face uncertainty in terms of differences between over-simplified models described in tender documents and the reality of full-scale construction and the apportioning of geotechnical risks. It is not easy to document intrinsic geological variability, the spatial variation in geotechnical parameters, rock mass quality variations, the existence of anomalies such as boulders or voids, and the differences between laboratory sampling/testing and in situ behavior. A valuable tool for assessing spatial variability and uncertainty is geostatistics. Geostatistics not only helps predict geotechnical parameters but also plays a crucial role in ground risk management. By quantifying uncertainty in spatial distribution of soil and rock properties, engineers can better plan for potential risks and variability in construction phases. This paper presents the successful implementation of geostatistics in enhancing the geotechnical understanding and designs for the relocation of fresh and saltwater service reservoirs to caverns at Diamond Hill.
