River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
Functional Specifications of a Distributed Engineering Data Management System
The development of a large-scale engineering data management system is outlined for AEC industries. Described are the outline specifications and basic design decisions used to implement...
Advances in CAD for Structural Engineers
In the 1980's Computer-Aided Design (CAD) will offer the structural engineer an opportunity to improve his work. Decreases in the cost of equipment and improvements in computer-aided...
Relational Model for Computer Analysis and Design
One of the most critical elements in engineering analysis and design is data management. Relational database systems have been proven to be an excellent tool for managing the voluminous...
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...
Selfweight Consolidation of Very Soft Clay by Centrifuge
This paper reports a series of selfweight consolidation tests and their analysis by Mikasa's consolidation theory. The tests covered a coastal reclamation project and the...
The Use of Soil Mechanics Capabilities in a General Purpose Finite Element Program
This paper describes capabilities, points out features of implementation in a general purpose code, and describes some numerical considerations. The paper makes use of illustrative solutions....
Validation of Consolidation Properties of Phosphatic Clay at Very High Void Ratios
The void ratio-effective stress and void ratio permeability relationships for phosphate slime mine tailings were measured by several methods. The measurements were used in nonlinear finite...
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 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...
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...
Trends in Computerization in the Eighties
This paper addresses trends in computer-aided productivity tools for Civil Engineers in the eighties. Certain aspects of the past history, present status, and future of CAD/CAM and CAE...
Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...
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...
Impacts of an Overboard Disposal Operation
The objective of this study was to establish an acceptable dredge disposal site which would be physically and environmentally suitable for periodic use over the 50-year project life of...
Dredged Material Disposal Modeling - Chesapeake Bay
A plan to deepen the approach channels to Baltimore Harbor from 42 feet to 50 feet involves in part the overboard disposal of about 9. 5 million cubic yards of dredged material in the...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
