A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...

Dynamic Stiffness of Pile Groups
A number of procedures have been proposed for the dynamic analysis of complete pile foundations including group effects. Most of these introduce some sort of approximation to reduce the...

Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...

Study on Secondary Compression of Clays
An elastoviscoplastic constitutive model shows that a strain rate effect parameter is related to the coefficient of secondary compression. The relation was verified experimentally by test...

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...

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...

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...

Charlotte Harbor Beach Nourishment
The project consisted of dredging approximately 300,000 cubic yards (229, 380 cubic meters) of material, utilizing a seagoing hopper dredge, from the entrance channel of Charlotte Harbor,...

Management Plan for Dredged Maintenance Material
The Mobile District Corps of Engineers is responsible for the maintenance of an authorized Federal deep-draft navigation project at Pascagoula Harbor, Mississippi. The development of the...

Modeling the Drying of Dredged Material
The drying of dredged material was modeled mathematically as a diffusive process and the governing equation was solved using an integral method. Closed form solution equations are presented...

Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...

Plant Bioassay of Contaminated Dredged Material
Contaminant mobility from a contaminated saltwater sediment placed in flooded and upland disposal conditions was studied in the greenhouse. Spartina alterniflora was grown in contaminated...

A Biogeochemical Evaluation of Disposal Options
This paper briefly reviews some of the factors that should be considered in selecting an environmentally sound disposal method for contaminated sediments on the basis of the biogeochemical...

Evapoconsolidation in Fine-grained Material
The increased difficulty of obtaining land needed for confined disposal of dredged material and phosphatic clays highlights the need to assess alternative disposal measures by accurately...

Surface Runoff Water Quality from Contaminated Dredged Material Placed Upland
Bioassay and associated tests have been developed and are being refined to assist in the evaluation of the environmental impact of dredged material disposal alternatives. Simulated rainfall-surface...

Safe Landfilling of Contaminated Dredging Spoil
This paper deals with the assessment of the expected emissions of toxic substances from highly contaminated harbor dredged material. The material in question arises from the canal between...

Aquatic Bioassays in Dredged Material Management
Dredged material ranges from gravel and coarse sand to fine silts and clays, and may be free of contaminants or highly contaminated with a variety of chemicals from industrial, municipal,...
