The proceedings of the 1989 ASCE Foundation Engineering Congress (entitled Foundation Engineering: Current Principles and Practices) address advances in the state-of-practice and in research...
Predicted and Observed Axial Behavior of Piles
Results of a Pile Prediction Symposium
This publication presents the results of a pile capacity event that was held at the Lakefill site on the Evanston Campus of Northwestern University in conjunction with the 1989 Foundation...
Quick Response on the Mississippi
In November 1987, the Mississippi River broke through the foundation of the St. Anthony Fall's Lower Dam Hydropower Plant. The plant's owner, the Northern State...
Preventive Maintenance: Fixing What Ain't Broke
Municipalities are often caught in the cycle of built-neglect-rebuild. For bridges, the solution is preventive maintenance: keep the bridges clean and painted, and they'll...
Transferring Construction Innovation into Practice: Lessons Learned
The paper presents several cases that illustrate the value of a systems approach in the need for aggressive and persistent exploitation despite early set-backs, and the unsatisfactory...
Bells Under Bells
Chicago's newest office tower is supported on new bells that had to be constructed below existing belled caissons. Existing caisson foundations from a previous structure on...
Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...
Cedar Falls Project-Rehabilitation with RCC
This paper presents an overview of the planning, design, and construction considerations used during the development of the 9. 1 m (30-foot-high) Cedar Falls Roller Compacted Concrete...
Geotechnical Exploration?Rio Bravo Hydro Project
In order for the Rio Bravo Hydroelectric Project to become a reality, a thorough evaluation of alternative project configurations was necessary. Various power canal shapes, sizes, and...
Summer Falls High Head Kaplan Turbine Project
The Summer Falls Project is located on the Main Canal of the Grand Coulee Irrigation Project approximately eight miles south of Coulee City in Grant County, Washington. The power development...
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,...
Roller Compacted Concrete Dams?An Overview
The development of roller compacted concrete for gravity dams is traced from forerunners, through its use at the Shihmen and Tarbela Dam Projects to Willow Creek Dam and the Japanese Roller...
Planning, Design and Cost Estimates for RCC Dams
Engineers, planners, and officials of agencies responsible for developing water resource projects are confronted with preparing preliminary designs and cost estimates for dams. This paper...
Cedar Falls Roller Compacted Concrete Dam
This paper presents the design, material testing, quality control, and construction considerations applicable to a small Roller Compacted Concrete (RCC) dam. The Cedar Falls RCC dam is...
Roller Compacted Concrete Design for Urugua-I Dam
Gravity dam construction by the roller compacted concrete method (RCC) has received widespread interest following completion of Shimajigawa Dam in Japan (1981) and Willow Creek Dam in...
Karstic Foundation Problems Sunny Point Railroad
Active limestone sinkholes have been causing problems and affecting the operation of the access railroad to the Military Ocean Terminal, Sunny Point, North Carolina (MOTSU) since 1962....
The MPSP System: A New Method of Grouting Difficult Rock Formations
In unstable rock masses the traditional stage grouting methods may prove impractical or ineffective. A recent innovation has been the Multiple Packer Sleeved Pipe (MPSP) System. Akin to...
Foundation Treatment of Karstic Features Under TVA Dams
TVA has constructed many of its dams on limestone foundations. Some of these foundations have been highly weathered and required special treatment not only to ensure strength but to develop...
