Abstract:

Current practice in the characterization of subsurface conditions usually involves the interpretation of data from lab and in-situ tests using deterministic analysis methods. These methods do not reflect the uncertainty inherently associated with the estimation of geotechnical parameters. Also, there are no commonly accepted methods for evaluating the quality of the investigation or estimation of the impact of additional sampling in a quantitative manner. This paper describes the development and implementation of a performance-based investigation and monitoring approach to assess the quality, or thoroughness, of site investigation and monitoring activities in a quantitative, spatially sensitive manner. Thoroughness images are based on probability values generated using geostatistics and are designed to enable users to better assess the likelihood that design or regulatory criteria will be met. The approach was implemented within a GIS and was evaluated using an existing geotechnical data set.
