Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...

Construction and Design of Foundations for French Overhead Power Transmission Network
This paper summarizes present conception and design of foundations for 90 to 400 kV overhead lines in France. Firstly principles of geotechnical studies in use are presented: various types...

High Capacity Multi-Helix Screw Anchors for Transmission Line Foundations
Three case history summaries are presented which discuss the siting, design, and construction of towers supported on multi-helix screw anchor foundations in the Virginia Power service...

Settlement of Residual Soils
The method previously suggested by the author in 1977 for calculating settlement of non-plastic to slightly plastic Piedmont Physiographic Region residual soils is reviewed. Additional...

Pressure Injected Footings in Piedmont Profiles
Comparatively little has been published on the behavior of pressure injected footings in the Piedmont residual soils and weathered rocks. It is the purpose of this paper to describe some...

Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...

Dispersive Soil and its Influence on the Design of Reach 1A of the Tucson Aqueduct?Central Arizona Project
An extensive geotechnical field exploration and laboratory testing program was conducted because of dispersive and erosive soils along the alignment of the canal. The canal design was...

Risky Waters
Risk assessment is a tool engineers use to clarify the impact and issues associated with various choices and perspectives. Because problems and projects related to water have such a significant...

Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...

Embankment Over Fly Ash Pond at Portsmouth Power Station
The fly ash and bottom ash sediments from the Portsmouth Power Station in Portsmouth, Virginia were being sluiced into a 39 acre diked ash pond near the plant. The plant was about to convert...

Foundations for Transmission Line Towers
This special technical publication contains the proceedings of a two session symposium on foundations for transmission line towers. These papers were written by researchers, geotechnical...

Dynamic Response of Pile Foundations?Experiment, Analysis and Observation
In recent years, a considerable amount of attention has been paid to the dynamic response behavior of pile foundations. However, mainly because of difficulties in conducting tests and/or...

Foundations and Excavations in Decomposed Rock of the Piedmont Province
The five papers in this volume deal with foundations and excavations in the Piedmont Province of the USA. This is a region underlain by very old metamorphic rocks that are overlain by...

Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...

Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...

Stepped Spillway Design with a RCC Dam
The hydraulic model study results for the Upper Stillwater stepped spillway design are presented. The studies encompassed several spillway geometries and design unit discharges ranging...

Hydraulic Structures on Piles
Many hydraulic structures built in the early 1900's were founded on piles. Today, when these structures are analyzed as 'pile-supported', the analyses...

Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...

Underwater Inspection of Hydraulic Structures
Improvements in diving equipment, and underwater testing and instrumentation devices in recent years have increased the value of underwater inspections and reduced the cost. This paper...

Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
