The Geotechnical Engineering Investigation Handbook provides the tools necessary for fusing geological characterization and investigation with critical analysis for obtaining engineering design criteria. Updating this pioneering reference for the 21st century, this second edition reflects the technological developments that have occurred in the 20 years since the first edition was published. By using a practical approach to problem solving, this book helps engineers consider geological phenomena in terms of the degree of their hazard and the potential risk of their occurrence.
