Foundations on Expansive Soils in Northern Virginia
Thick layers of clayey silts (MH) were observed at several sites where townhouse developments were planned. These deposits had a high shrink swell potential. Maximum swell pressure tests...
Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...
Power Pole Foundations in Reclaimed Mining Area
In central Florida, where strip mining for phosphate ore is a primary industry, street surfaces often become rolling because of differential settlement, and electrical transmission poles...
Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...
Consolidation Grouting Operations for Kirkwood Penstock
Kirkwood Penstock, which is part of the Hetch Hetchy water system of the City of San Francisco, California exhibited evidence of settlement and local extension following extraordinarily...
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...
Ground Modification for a 14-Story Structure Over a Deep Peat Deposit
The foundation design and construction for a 14-story reinforced concrete office building northwest of Minneapolis is described. The building's geometry provided unusual foundation...
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
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...
Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...
Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...
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...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Contribution of Soil Freeze to Pile Capacity
In order to investigate the magnitude and rate of increase in load capacity for piles installed in clayey soils, a series of load tests were performed at various intervals of time following...
Load Tests on Bored Friction Piles in Clay
For the first time in Boston, Massachusetts, U.S.A., uncased bored friction piles in clay were used to support a six-story residential structure over a 60- to 75-foot (1.83 to 22.9 m)...
Full Scale Caisson Load Test for the Milwaukee Center
Top-down procedures were proposed to construct four basement levels for a major high-rise building development in Milwaukee, Wisconsin. Drilled caisson foundations were the preferred means...
A Lateral Load Test on Seven Foot Diameter Caissons
Seven foot (2.1 m) diameter caissons (drilled shafts) were designed to support a mainline eastbound bridge and an off-ramp of Interstate Highway 70 in Glenwood Canyon, Colorado. A lateral...
Geophysical and Nuclear Methods for Non-Destructive Evaluation of Caissons
Non-destructive testing techniques were used to confirm the concrete integrity on the caisson foundations for the 45-story Ohio Corporate Headquarters building in Cleveland, Ohio. The...
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...
