Analysis of Drilled Shafts in a Deep Fill
A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must...
Special Bedrock Conditions and a Foundation Project in Greater Boston
In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing...
Underwater Foundations for a Jack-up Barge
Innovative underwater foundations were developed to provide a solid base for the legs of a large jack-up barge needed by General Dynamics to transport heavy components from Quonset Point,...
Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...
The Role of Analytical Geomechanics in Foundation Engineering
The role of modern geotechnical analysis in foundation design is reviewed, and analysis methods are classified into three categories, depending on their level of sophistication. The benefits...
Structural Design, Analysis and Testing
This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...
The Water Erosion Prediction Project: Erosion Processes
The erosion process on hillslopes is conceptualized in the USDA Water Erosion Prediction Project (WEPP) as being divided into rill and interrill processes. Rill detachment occurs when...
Derivation of a Stability Principle from the Shields Criterion
The widely used specific energy equation, which defines the subcritical and supercritical states of the open channel flow, is a direct result of the integration of the Froude number corresponding...
Mathematical Models for Turbulent Shear Stress in Sediment-Laden Flows
Turbulent shear stress in sediment-laden flows has been examined by several investigators including H.A. Einstein and N. Chien A. Zagustin and J.C. Willis. Three derivations resulted in...
Towards a Distinct Treatment of Incipient Motion for Bed Forms of Low Regime
The principle methods for estimating the incipient particle motion on developed bed forms in the lower regime are compared with each other. Usually only a part of the total wall shear...
The Beginning of Sediment Transport as a Probability-Problem
Sediment transport only takes place when the action of flow (shear stress, velocity) exceeds a critical value. The limit between rest and movement can be given as critical flow velocity,...
Critical Shear Stress of Armour Coat
The problem of the determination of the critical shear stress of the armour coat is important in sediment transport, river degradation and aggradation and flow discharge regulation. The...
Sediment?Hyperconcentration Flow and Its Similarity Laws
The sediment- hyperconcentration flow are studied theoretically and experimentally, and the formulas for the Bingham shear stress, rigidity coefficient, fall velocity and transport capacity...
Flow Modeling in the Toutle River, Washington
In support of flow, suspended load, bed load, and bedform transport measurements, a quasi-three-dimensional river flow model was adapted to a reach extending from 260m upstream to 30m...
Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...
Interfacial Instability in Highly Stratified Flows
The stability of highly stratified shear flows is dependent on several parameters including the thickness of the interfacial transition layer. Experimental results show that the thickness...
Overfall Stress and Pressure Distributions
The magnitude and distribution of hydraulic shear stress and pressure on the boundary of a straight drop overfall are presented for multiple overfall heights and flow rates. Hydraulic...
A
A two-component turbulence model is introduced for depth-average flow calculations in shallow open-channel flows. This model treats the bed-generated turbulence as a background component,...
Analysis and Rehabilitation of Ambursen Dams
This paper deals with the investigation and analysis of two Ambursen dams located in the upper Midwest. These investigations revealed that the original design contained significant defects,...
In-Situ Shear Strength Testing
Dam stabilization requirements at the Upper Mechanicville Hydroelectric Project on the Hudson River in New York were significantly modified based on the results of an in-situ direct shear...
