Evaluation and Control of Expansive Soils

摘要

The 11 papers in the report deal with the following areas: rational approach to predict swelling soil behavior; spatial characterization of expansive clays; measurement of swelling pressure in the laboratory and in situ; prediction of swelling pressure and factors affecting the swell behavior of an expansive soil; role of mineralogical composition in the activity of expansive soils; treatment of expansive soils; a laboratory study; foundation design of an industrial plant in stillwater, Oklahoma; controlling expansive soil destructiveness by deep vertical geomembranes on four highways; long-term behavior of a drilled shaft in expansive soil; experience with roads and buildings on expansive clays; and, the effect of vegetation transpiration on the deformation of high void ratio expansive soil foundation.
