Geotechnics of High Water Content Materials
Construction on marginal lands is becoming increasingly necessary for economic reasons. Foundation soils for these projects, such as soft clays and peats, typically have high water content, high com-pressibility, and low shear strength. There is also considerable interest in the economic and environmentally safe disposal of high water content waste materials. Applications in which waste materials
can be reused beneficially take on even more importance. The successful design, construction, operation, and in some cases reclamation of such projects involve predictions of geotechnical behavior in terms of hydraulic conduction, settlement, and shear strength, often as a function of time.
This, in turn, requires reliable material characterization and modeling that accounts for differences in behavior as compared to conventional soils. Likewise, there is a need for laboratory and field tests to measure material properties and, in some cases, a need for specialized techniques of construction.
