Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
Comparison of Caisson Load Tests on Chicago Hardpan
The results from two relatively recent instrumented caisson load tests from different sites on Chicago Hardpan are compared with a 'classic' large scale caisson...
Observations on Load Tests for Drilled Shafts
This paper focuses on three specific areas pertaining to load tests for drilled shafts: 1) basic considerations and load testing procedures, 2) interpretation of uplift load test information,...
Review of Repeated Axial Load Tests on Deep Foundations
A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general,...
Construction Management: Dallas North Tollway Project
This article will attempt to illustrate the importance of flexibility of the design and construction inspection process to insure the project is constructed within the time and budget...
Embankment Seepage Control Design and Construction
For seepage control features of embankment dams, design criteria and construction practice is reviewed as it is reflected in the experience of the U. S. Army Corps of Engineers. The generally...
Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
Seepage Control at Cochiti Dam, New Mexico
Significant design data, design assumptions and computations, and performance of the seepage control features provided at Cochiti Dam are summarized in this paper. The dam is a rolled...
Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
The Use and Performance of Seepage Reduction Measures
The utilization and performance of various foundation seepage reduction measures from over 100 dams situated on pervious soils throughout the world has been reviewed. Summary discussions...
Designing and Monitoring for Seepage at Calamus Dam
Given the complex, pervious nature of the foundation for Calamus Dam, every effort has been made to incorporate design features that will reduce and control the anticipated large volumes...
Use of Asphalt in Treatment of Dam Foundation Leakage, Stewartsville Dam
This paper presents the recent development and application of a hot asphalt grouting technique used to stop a 5,000 Imperial Gallons Per Minute (IGPM) (22,000 lpm) dam leakage under full...
Computer Applications in Grouting
The first use of computers during foundation grouting was tried by the Bureau of Reclamation on Ridgeway Dam in Colorado. It was very useful in monitoring real time down hole conditions...
Computer-Assisted Grouting Evaluation Systems
Electronic monitoring of cement pressure grouting at Ridgway Dam provides a powerful tool for geologic assessment of drilling and grouting results. Graphic surveillance and analysis of...
Grout Slurries?Thick or Thin?
In this paper some recent experiences in dam grouting in several countries are discussed where bentonite or Intraplast additives were used to control sedimentation, viscosity, grout density,...
Application of Displacement of Discontinuity Methods in Underground Mine Design
Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983),...
Prediction of Highway Construction Noise Levels
A model for the prediction of noise levels from highway construction operations has been developed under sponsorship of the Federal Highway Administration (FHWA). Noise sources are geometrically...
Highway Noise: FHWA Requirements and Barrier Design
Since 1973, the Federal Highway Administration (FHWA) has required noise studies for nearly all proposed roadways and roadway improvements that receive federal aid. An overview of these...
Cost-Effective Design of Practically Vibration-Free High-Technology Facilities
Advanced electro-optical equipment, such as that used in the production of integrated circuits, requires clean environments with extremely limited vibrations. Ground motions, personnel...
Site Selection and Building Design for Minimizing Vibration
Over the last five to ten years, line resolutions required for state-of-the-art semi-conductor wafers have dropped to well below 1 micron. As a result, controlling environmental building...
