Consolidation of Mining Wastes
This paper describes laboratory and field tests for determining consolidation properties of soft sediments, presents data on several types of mining wastes, and presents the results of...
Perspectives on Modelling Consolidation of Dredged Materials
The physical and mathematical aspects of this problem are highly nonlinear and material-property relationships extend beyond the scope of standard geotechnical engineering. The potential...
Logan Airport Re-Visited
The first detailed evaluation of self-weight consolidation of a large hydraulic clay fill was performed during the construction of Logan Airport in Boston nearly 40 years ago. The paper...
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Yield Behaviour and Consolidation. II: Strength Gain
In Part I it was shown that in situ yielding of soft foundation clays significantly affected consolidation behaviour and that yield could be defined using the effective stress path/yield...
Consolidation of Permafrost upon Thawing
Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures...
Prediction of Peat Settlement
Compression of peat and organic clay deposits is characterized using a simple rheological model in which structural viscosity is assumed to be linear. The model utilizes three empirical...
Time and Stress Dependent Compression in Soft Sediments
Results are presented for laboratory experiments using a typical estuarine mud settling from a slurry in columns of 100mm diameter. Measurements have been made of density and pore water...
Instrumentation Performance in Soft Clay Soils (A Case History)
In 1978, IDEAL BASIC INDUSTRIES, INC. initiated construction of a cement manufacturing plant located south of Mobile, Alabama on the Theodore Ship Channel. Because deltaic clays were too...
Sedimentation and Self Weight Consolidation of Dredge Spoil
Test results suggest that self weight consolidation begins when an interface forms in the settlement column and the slurry reaches a critical concentration as a result of the solid particles...
Dredged Slurry Stabilization for Seagirt Marine Terminal
The Seagirt Marine Terminal is constructed on reclaimed land on dredged spoil from the I-95 Fort McHenry Tunnel in Baltimore, Maryland. Three stabilization procedures considered applicable...
Prediction of Viable Tailings Disposal Methods
A sand-fines-water diagram is proposed to analyze and describe slurries composed of coarse and fine particulate matter. The diagram can be used to predict and plan disposal methods for...
Waste Phosphatic Clay Disposal in Mine Cutsr
Research was undertaken to assess the applicability of waste clay disposal back into phosphate mine cuts. The pit was monitored for two years with measurements of clay surface elevation,...
Centrifugal Modeling of Phosphatic Clay Consolidation
As a by-product of beneficiation, quantities of dilute clay slurry are produced which are stored in retention ponds. One method of accelerating consolidation is to surcharge the clay with...
Monitoring of an Ocean Dredged Material Disposal Site
The Tampa Harbor Project involves deepening and widening approximately 50 miles of existing shipping channel in Tampa Bay, Florida, with the removal of approximately 70 million cubic yards...
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
Offshore Dredging - Is it still Cost Effective for Beach Restoration?
Offshore dredging has been the source of sand for beach restoration in southeast Florida since Broward County constructed the first project in Pompano Beach in 1970. However, with increasing...
Land Application of Dredged Material at Port Manatee
Maintenance dredging of approximately 600,000 cu yd of highly plastic clay was conducted in October 1983. This material was deposited on a nearly 200 acre tract of farmland in a depth...
Agricultural Crop Production and Quality Effects when Soils are Amended with Dredged Lake Sediments
Lake renewal achieved by pumping loose sediment from the lake bottom requires a disposal area for that sediment and the associated water. Application of this sediment to agricultural land,...
Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...
