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...
Long Term Performance of High Rise Mat Foundation
The vertical movement of the foundation soils for a multi-story high rise office tower was monitored during foundation excavation, tower construction and the 25-year in-service period...
Complex High-Rise Foundation Design and Construction
The substructure design and construction of a 60 story office tower in downtown Chicago is described. The presence of existing belled caissons on hardpan required use of filtered dewatering...
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....
Response of Concrete Island Drilling System to Ice Impact Loading
The lateral stability and load/deformation characteristics of the Concrete Island Drilling System structure under ice impact loading conditions were studied. The 300-foot-square (91.5-meter...
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...
Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...
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...
Reliability in Foundation Engineering Practice
The value and use of reliability concepts in foundation engineering practice are explored, with a focus on two complementary approaches. In the first, macroscopic and action-oriented,...
Dredge Disposal Monitoring by Fourier Shape Analysis
Fourier grain-shape analysis characterizes a population of sediments in terms of the shapes of the grains. The technique of grain-shape analysis has been successfully applied to the area...
Conducting a Waterline Corrosion Evaluation
A study has been conducted to determine the level of corrosion activity occuring on the U.S. Navy's potable waterlines on Guam. The study evaluated soil parameters including...
A Method for Design and Evaluation of Rapid Sand Filters Treating Secondary Effluents
The information presented in this paper provides a framework for analysis of rapid sand filter performance. Process variables are quantitatively related to filter design variables in a...
Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
Estimating Soil Gas Flow Rates and Identifying Entry Routes in a Dwelling Using Multiple Perfluorocarbon Tracers
Passive monitoring of indoor air and below basement floor (subslab) soil gas for radon and perfluorocarbon tracer (PFT) gas concentration was conducted to investigate the influence of...
Indoor Radon: Site Evaluation
The soil parameters most important in evaluating the indoor radon potential of a building site are the soil radium concentration, the soil-gas radon concentration and the permeability...
Pressure Differences Affecting Radon Entry in New Residential Construction
Various conditions in a house can commonly produce house negative pressures up to 20 Pascals relative to the soil gas pressure. Depressurization of the house relative to the soil gas will...
Instrumentation of Landfill Cover Liners: Moisture Transport Studies
Accurate estimation of the amount of water leaking through the cover liner, into the landfill, is vital for estimating the possible amount of leachate that can be generated into a landfill...
Ft. Huachuca, AZ Fire Site Hazardous Waste Remedial Action
The paper discusses an investigation of the site of a major fire at Ft. Huachuca, Arizona. All of the fire debris contained asbestos. The sampling results confirmed that PCB levels of...
