摘要：	An indication of current sampling and strength-testing practices in stiff, overconsolidated clays across the United States has been obtained from a nationwide survey of private geotechnical consultants, state and federal highway engineers, and academic institutions. A diversity of sampling techniques, laboratory tests, and in situ field measurements is used in practice depending on the particular geologic setting, local conditions, economics, and experience. Problems involving overconsolidated clays appear primarily related to the proper site characterization and the determination of soil properties for analyses of slope stability, pile foundations, high shrink-swell subgrade soils, and deep excavations. Recent advances in laboratory procedures and in situ testing offer alternative means of assessing the stress-strain-strength behavior of stiff to hard and fissured clays, leading to better economy, reliability, and productivity.
