Foundation Engineering in the Face of Uncertainty, GSP 229, honors Fred H. Kulhawy, Ph.D., P.E., G.E., Dist.M.ASCE, for his many contributions advancing the science, art, teaching, and practice of geotechnical engineering. Dr. Kulhawy has influenced the civil engineering profession worldwide with his willingness to share his knowledge and expertise in many areas of geotechnical engineering including soil and rock mechanics, foundation engineering, and engineering geology. This collection contains 54 papers that explore uncertainty in foundation engineering, including characterization of soil parameters, spatial variability, uncertainty and risk analyses, reliability analysis, and reliability-based design. Seventeen papers are reprints of classic papers authored or co-authored by Dr. Kulhawy, and 37 invited technical papers are contributions by experts from around the world, which also include informative case histories. Foundation Engineering in the Face of Uncertainty contains practical and technical information on risk and reliability in foundation engineering that will be of interest to geotechnical engineers, foundation specialists, engineering geologists, and researchers.
