Abstract: A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model is used which incorporates prior information with the sparse data to develop more realistic descriptors for the uncertainty in the geotechnical properties. Suggestions are given for optimal usage of the prior information and the data, and examples are presented of the Bayesian model with illustrative site data.
