On Cyclic Testing with Thin Long Hollow Cylinders
The hollow cylinder device has emerged in recent years as an important tool in the investigation of the dynamic behavior of soils. This paper reviews the stress conditions present in the...
Cyclic and Monotonic Undrained Response of Saturated Sands
A unified picture of the undrained monotonic and cyclic loading response of saturated sands is presented. A wide range of initial states of sand are covered in order to consider a full...
Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...
Evaluating Nonlinear Soil Behavior Using the Resonant Column
An analysis is presented that attempts to match a mathematical model to the nonlinear behavior obtained from the resonant column test. This model consists of an oscillator with a restoring...
Uplift Behavior of Shallow Soil Anchors?An Overview
An overview is presented of the static uplift (tensile) behavior of shallow anchors used for foundations in soil. Basic anchor types are described, and their general installation and behavioral...
A Space Frame Forecast
New York City's Jacob K. Javits Convention Center has the largest space frame of its kind in the world. There are several unique design features in the space frame, among...
Solutions in the Pipeline
Water and sewer agencies across the country are beginning to feel more comfortable about pipeline rehabilitation. Where once replacement was the ony alternative considered for aged, clogged...
Private Funds, Public Projects
Tapping private sources for public services is not new, though the concept has advanced from traditional contracting for services, which has been around since pre-Revolutionary War days....
New Safety for Old Dams
Shortly after the Phase I inspection program conducted by the U.S. Army Corps of Engineers in 1978-81, the Pennsylvania legislature authorized $300 million for repair of dams, ports and...
Hurricane Alicia
One Year Later
In the pre-dawn hours of August 28, 2983, Hurricane Alicia ripped its way ashore at the western tip of Galveston Island and moved northward to the Greater Houston area. This storm caused...
Development and Management Aspects of Irrigation and Drainage Systems
The 1985 Irrigation and Drainage Division Specialty Conference held in San Antonio, Texas on July 17-19, 1985 covered major topics on watershed management and water conveyance, drainage...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Environmental Engineering
The purpose of the annual Conference on environmental engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of environmental...
The PowerBarge Hydroelectric Plant
Following an account of the need for such an approach, the PowerBarge hydroelectric plant design concept is described as a fully floating system consisting of an Intake Barge, Siphon Penstock,...
Membrane Sealing of Rouchain Dam
A synthetic sealing membrane was used to prevent excessive leakage through the facing of an embankment dam. The works, which were completed rapidly and at low cost, enabled the reservoir...
Concrete Face Rockfill Dams of the Winneke Project
Two of the three dams forming the Winneke Reservoir, near Melbourne, Australia, are concrete face rockfill dams. A minor dam forming the sludge storage pond for the project's...
Mangrove Creek Dam: Use of Soft Rock for Rockfill
Mangrove Creek Dam is an 80 m high concrete faced rockfill dam (CFRD) completed in 1981. The embankment was constructed largely out of low strength sandstones and siltstones available...
Design of Concrete-Faced Rockfill Dams
Design principles adopted in 1966 by the Hydro-Electric Commission have been applied to nine concrete-faced rockfill dams and remain substantially unchanged. Experience shows that the...
Seismic Design of Concrete Faced Rockfill Dams
The results of analytical studies of the stability of the slopes of concrete-faced rockfill dams under different levels of earthquake shaking are presented and used to propose desirable...
It? Dam?Selection of Type
This paper describes the studies carried out for the type of dam selection for the Ita Hydroelectric Project. Drastic rainfall conditions, large river diversion flows and an abundance...
