Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
Owner and Designer Advantages Derived from Use of Construction Consultant
There are two significant ways that an experienced construction consultant can assist both the owner and the designer/engineer in obtaining an economical and practical structure. Constructibility...
Some Observations on Undrained Side Resistance of Drilled Shafts
A data base of 106 field load tests (65 in uplift and 41 in compression) is used to evaluate the undrained side resistance of drilled shaft foundations. The total stress or alpha (?) method...
Performance of a Large Ribbed Mat on Cohesive Soil
The performance of a 678-ft by 304-ft (207-m by 93-m) ribbed concrete mat was studied to provide improved soil input parameters for design. The mat was constructed on a low plasticity...
Performance of Different Retention Systems in Similar Soils
Performance behaviour of three deep braced excavations in a similar soil profile, in the Chicago area is described. At each site, different bracing systems were utilized. Methods used...
Field Performance of a Soil Nail System in Loess
This paper presents data from measurements of a soil nail system constructed in loess soil in Pullman, Washington. The soil nail system is designed to retain a 39.2 ft (11.9 m) high excavation...
Pile-Drilled Caisson Combination for Foundation of High Rise Building
The analysis and evaluation of several alternatives for foundations of a high rise office building is presented, which resulted in the selection of a combination of high capacity piles...
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...
Combination Drilled Shaft and Driven Pile Foundation for a High-Rise Building
A case history is presented which discusses the design and construction of a combination drilled shaft and driven pile foundation which supports a high-rise in San Francisco. Drilled piers,...
Performance of a Building Foundation Designed to Accommodate Large Settlements
The Eastern Airlines shuttle terminal at LaGuardia Airport in New York City is supported on spread footings founded in an incinerated refuse fill which overlies a deep deposit of slightly...
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...
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...
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,...
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...
Integration of Research Into Design Practice
A widely held perception is that research results flow from the research community along the paths of professional publication into the design offices, where they find practical application....
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...
A Case Study of Ebb Tidal Delta Equilibrium: Ocean City, Maryland
The inlet at Ocean City, Maryland was created by hurricane surge breaching of Fenwick Island Spit in 1933. Inlet stabilization was completed in 1934-1935. The inlet jetties have been held...
Fouling and Wood-Boring Communities Distribution on the Coast of Rio De Janeiro
The paper reports on a study of the dynamics of fouling communities and the distribution of wood-boring organisms along the coast of Rio de Janeiro, Brazil, which was motivated by the...
