Description:
The behavioral characteristics of hydraulically placed maintenance dredgings were investigated during an extensive four-year field and laboratory experimental program. The field work, which took place primarily at four disposal areas near Toledo, Ohio, consisted of (a) periodic vane shear strength determinations, (b) obtaining undisturbed tube samples for subsequent laboratory tests, and (c) the measurement of in-situ permeability values. The laboratory testing program included the evaluation of time-dependent (a) volume changes by means of slurry consolidation, conventional consolidation and long-term secondary compression tests, (b) strength determinations by use of a miniature vane, fall cone, and unconfined compression tests, and (c) various classification tests. Based on an extensive series of classification tests, it was found that the characteristics of the dredged materials deposited in each of the four sites were essentially the same, thereby enabling data from the different sites to be synthesized and interpreted as representative of one large site spanning a time period of almost a decade.
