Subsurface Conditions and Pile Installation Data: 1989 Foundation Engineering Congress Test Section

Geotechnical Judgment in Foundation Design
This paper summarizes the initial findings of a research project to investigate the judgment-making process of foundation engineers. Solutions for a typical design problem were solicited...

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...

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...

Subsurface Savings
Less conservatism than usual in designing building foundations is being accepted or demanded by some owners to save money. The article describes four examples of cost-cutting innovations,...

Exploration of Karst Conditions in Central Florida
Walt Disney World, which comprises some 28,000 acres (11,000 ha) in central Florida, is underlain by cavernous limestone and is characterized by karst topography; with distinct low ground...

Exploring Karst Terrain with Air Track Drilling
Pneumatic-powered track-mounted, percussion drills can be used to perform or augment geotechnical investigations in some karst settings. The air track drill is best suited to exploring...

Geotechnical Exploration and Site Preparation Techniques for Large Mall in Karst Terrain
A large commercial mall and secondary developments were planned for construction in a karst area near Clarksville, Tennessee. A geotechnical exploration was conducted to evaluate the occurence...

Internal Sealing of Large Diameter Pipelines
Underground piping has traditionally been repaired by making excavations at the joints and completing the repairs externally. However, with increasing labor costs, underground utility...

Irrigation Intervention Analysis of Drainage SAR
G.E.P. Box-G.M. Jenkins time series analysis, with irrigation applications as an intervention function, was used to study temporal and spatial variabilities of sodium adsorption ratios...

Investigation of Runoff from a Subsurface Drained Field
This paper examines the relationship among rainfall, water table level and runoff hydrographs for subsurface-drained farmlands. It was found that peak flows were greatly influenced by...

Atrazine in Subsurface Drain Water in Southern Louisiana
Atrazine was applied preemergent to corn on subsurface drained and undrained plots. Atrazine soil concentration and concentration and loss in drain water were determined for 243 days after...

Trace Elements and Pesticides in Salton Sea Area, California
Concentrations of numerous potentially toxic trace elements and pesticides were determined in water, sediment, and biota from the Salton Sea area in southestern California. Comparison...

Entrainment of Bed Sediment by Density Underflows
The erosion caused by a density-driven underflow has been studied experimentally. The observations indicate that a strong density current can entrain substantial amounts of bed sediment....

Utilization of Ground Penetrating Radar to Conduct Sediment Surveys of Frozen Reservoirs
The ground penetrating radar (GPR) system consisted of a control unit, antenna, recorder, a power supply on a sled towed by a snowmobile. A 120 Mhz antenna was utilized and gave excellent...

In-Place Properties of a Hydraulic Landfill

Recognizing Liquefaction Hazard
Technique for assessing liquefaction hazard are considered herein: Methods for compiling regional opportunity maps are reviewed and a crude national map is developed. Compilation of regional...

Effects of the 1985 Earthquake in Lazaro Cardenas, Mich.
An account is presented of a geotechnical survey made shortly after the major earthquake of September 19, 1985 (magnitude 8. 1) at the industrial port of Lazaro Cardenas in the state of...
