Consolidation Performance of Soft Clays: Part 1. Model
The simplified version of the soil model used in the finite element scheme is a linear anisotropic elastic model. Part 1 defines the parameters needed for the model and the laboratory...
Consolidation Performance of Soft Clays: Part 2. Predictions
The simplified version of the model described in Part 1 was used to predict the short-term performance of the St. Alban test fill. The long-term predictive capability of the model was...
Consolidation of Multi-layered Clay
Three kinds of clay with different plasticity were pre-consolidated from slurry and combined into typical two layered systems consolidated under 40 tf/m**2 with single drainage condition....
Consolidation by Sand Drain in Anisotropic Ground
The author reduces Biot's equations of consolidation into a single governing equation with the excess pore water pressure as the only unknown function and derives the theory...
Dredge Spoil Disposal Predictions and Performance: A Case History
A 146-acre dredge spoil disposal facility was constructed in Baltimore Harbor that received 3. 4 million cubic yards (2. 6 million cubic meters) of dredge spoil generated from construction...
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...
Repairing New York's Historic Bridges
The Brooklyn and Manhattan bridges are just two of New York City's venerable structures that are undergoing rehabilitation. Current work on the Brooklyn involves enlarging...
