A New Combined Footing and Drilled Shaft Foundation Design
A conventional belled caisson foundation installation in glacial till to support a suburban Chicago 10-story office building was stopped when test caissons revealed excessive water-bearing...
Sensitivity Study of the Cyclic Axial Capacity of a Single Pile
Evaluation of the axial capacity of an offshore pile subjected to a severe North Sea storm is presented. Effects of using different degradation criteria, upper and lower bound interaction...
Design, Construction, and Load Testing of a High Capacity Caisson
This paper describes the large diameter caisson foundation for the upstream guidewall at the Lock and Dam No. 26 (Replacement) Project. The guidewall is supported on two rows of 6-foot...
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,...
Axial Capacity of Pressure-Injected Piles: A Cavity Expansion Model
The application of cavity expansion theory to the development of a mathematical model for predicting the ultimate axial capacity of pressure-injected piles in cohesionless soils is presented....
Innovative Foundation Designs for Permafrost Conditions in the Arctic
This paper describes the engineering solution to restore the structural properties of permafrost at a site location in the Western Operating Area of the Prudhoe Bay Field. Steel pile supports...
Loss of Carrying Capacity in Pipes?Transporting Softened Water with High pH
The increase in pipe roughness and loss in carrying capacity for water mains carrying high pH water is documented with over 20 field tests conducted in Austin, Texas. The data show that...
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...
Determining Hydro Project Dependable Capacity
Traditional techniques for estimating a hydro project's dependable capacity are of limited value when evaluating a hydro project in a thermal-based power system. For such...
Quantifying Uncertainty in Hydropower Planning
Power system operators must deal with various types of uncertainties. Some are related to inputs, such as system load and water supply, while others pertain to the system itself, such...
Foundation Engineering
Current Principles and Practices
The proceedings of the 1989 ASCE Foundation Engineering Congress (entitled Foundation Engineering: Current Principles and Practices) address advances in the state-of-practice and in research...
Predicted and Observed Axial Behavior of Piles
Results of a Pile Prediction Symposium
This publication presents the results of a pile capacity event that was held at the Lakefill site on the Evanston Campus of Northwestern University in conjunction with the 1989 Foundation...
Probabilistic Capacity Value of Nonfirm Hydro Energy
Electric utilities with a predominant mix of hydro generation traditionally apply Energy Planning criteria rather than Capacity Planning criteria in developing their generation resources...
Influence of Surface Finish on Thrust Bearing Life
The original pivoted pad thrust bearing installed and fitted at the Holtwood Power Station in 1912 by A. Kingsbury has been operating continuously since that time without any difficulty....
Shallow Foundation on Sand Underlain by Soft Clay with Geotextile Interface
One technique for improving the load-bearing capacity of shallow foundations on soft clay soil is to construct them over a compact granular fill laid over the clay layer. However, the...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
Probabilistic Prediction of Pile Group Capacity
A reliability analysis of a group of free standing piles in clay is carried out using Monte Carlo simulation. The pile material strength, soil capacity, and the load on the pile group...
Upper-Bound Estimate of the Reliability of Plastic Slabs
This paper gives a brief presentation of some recent results on probabilistic analysis of plastic slabs, especially reinforced concrete slabs. The estimate of the reliability of such slabs...
Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
Analysis of Bridge Truck Loads
The development of the reliability-based load and resistance factor design (LRFD) methodology requires uncertainties in loads and resistance be quantified. In the load capacity evaluation...
