Site Characterization of Yorktown Formation for New Accelerator
The design of a new 1700-m long continuous-wave electron beam accelerator facility (CEBAF) in Newport News, Virginia demanded an extensive geotechnical exploration program be conducted...
Collapsible Soils in the Antelope Valley�California
Soils subject to hydroconsolidation, commonly referred to as collapsible soils, have a potential to undergo significant volume reductions upon wetting, with or without additional loading...
Design Methodology for Foundations on Stone Columns
Stone columns offer the geotechnical engineer a valuable and viable technique for stabilizing sites underlain by soils ranging from soft clays to loose silty sands. A discussion of the...
Deep Soil Mixing at the Jackson Lake Dam
The Jackson Lake Dam was constructed in 1917 in the Grand Teton National Park near Jackson, Wyoming. The dam was a hydraulic fill placed on a natural alluvium and outwash foundation. The...
Settlement Characteristics from Insitu Tests in Flyash Structural Fills
Flyash from the Baltimore Gas and Electric Company's plants was used to construct structural fills in thickness ranging from 5 to 25 feet (1.5m to 7.6m). Several warehouses...
Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...
Model Tests for Bearing Capacity of Vertically Reinforced Foundations in Sand
Laboratory model test results for the bearing capacity of strip foundation supported by a sand layer with semi-flexible vertical rod reinforcements have been presented. All test results...
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...
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...
Bearing Capacity of Shallow Foundation on Granular Column in Weak Clay
Laboratory model tests results for the ultimate bearing capacity of shallow rectangular foundations supported by granular columns made in weak clay have been presented. In all cases, the...
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...
Chemically Induced Foundation Heave
The Kerr-McGee Electrolysis Plant in Henderson, Nevada has had recorded upward movements of portions of the building in excess of 18 inches. Contours of the measured heave indicate that...
Ponds and Lagoons of Gulf Islands National Seashore
A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...
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...
Geocosta Operations?A Program of Oceanographic Expeditions for the Brazilian Inner Shelf
In July 1979, a new expedition was conducted with the R.V. Almirate Camara, in the same area as GEOMAR X, with the following purposes: surveying profiles with side scan sonar and conducting...
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...
Structural Materials
This volume of Structural Materials contains papers from 12 sessions of the 7th Structures Congress held in San Francisco on May 1-5, 1989. The sessions cover a very broad range of topics...
Design of Plastic Piece Parts
This paper describes a computer assisted design process originally developed at the University of Wyoming and now implemented in commercial software. In order to address the need for broadly...
Stereolithography
Stereolithography is a three-dimensional printing process which produces accurate copies of CAD solid or surface models directly from CAD data. The process uses a moving laser beam, directed...
Gamma Exposure from Rn Progeny in GAC Units
An investigation into the gamma exposure rate generated by granular activated carbon (GAC) water treatment units focused on ten sites that covered a range of source radon (Rn) in water...
