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...

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 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....

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...

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...

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...

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...

Boundary Element Analysis of Flow in Heterogenous Porous Media
The boundary integral equation method (BIEM) is an efficient numerical method which has been applied to a wide variety of engineering problems governed by a partial differential equation...

Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...

A Nebraska Power District's Experience in Stabilizing by Silt Injection
The structures, rolled earth and concrete, of the Central Nebraska Project are constructed on foundations of loessial soils that range from a few feet to more than 100 feet in depth. The...

Thaw Settlement Analysis for Buried Pipelines in Permafrost
This paper focuses on determination of allowable thaw settlement for the design of cross country pipelines in permafrost areas. The purpose of the thaw settlement evaluation is to aid...

A Cost-effective Shallow Foundation Accommodates Three Feet of Settlement
An automotive maintenance facility to be built at the Anacostia Naval Station in Washington, D.C. had two major foundation problems: the probability of large settlement and the possibility...

Wicks, Fabrics and Sawdust Overcome Thick Mud
A new Dumbarton bridge is replacing the original which was built in 1927 to cross San Francisco Bay at its southern end. The bridge approaches are constructed on top of salt ponds, with...

101 Uses for Earth Reinforcement
A mini-symposium on earth reinforcement held at the April 1978 ASCE national convention attracted participants from around the world; symposium papers form the basis of this paper. Methods...

Sand to Sandstone: Foundation Strengthening with Chemical Grout
A large school in San Francisco, built in 1930, was in need of structural rehabilitation to eliminate earthquake hazards. Founded on loose, windblown fine sand, the footings were subject...

Pitfalls of Overconservatism in Geotechnical Engineering
The article cites at least three reasons why geotechnical engineers may be overconservative: (1) They may try to satisfy unreasonable standards established by themselves or others; (2)...
