Evaluation of PVC Bottom Linear From an Existing Landfill Located in a Subtropical Climate
Remedial action to curtail leachate seepage on a sanitary landfill located in a subtropical climate included the attachment of new PVC liner to an existing 20 mil PVC liner which has been...
Irrigation Canal Seepage and its Measurement
Reduction in seepage is one of the primary reasons used to justify investment in canal lining. Such justification depends greatly upon estimates of seepage through surface and subsurface...
Landfill Liner Hydraulics for Microcomputers
Two different models are presented for the study of sloping bottom liners for landfills. The first is based on the assumption that the leachate volume is uniformly distributed over the...
Two Projects Became One
Nontraditional funding and a new law were required before two Cortez, Colo. projects could be combined. Building a new canal and enlarging and lining an existing one to move water in essentially...
Construction of Mt. Baker Ridge Tunnel
Mt. Baker Ridge Tunnel is a large diameter soft ground highway tunnel constructed through sensitive over-consolidated silts and clays. Its large diameter necessitates the construction...
Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...
Foam Grout Saves Tunnel
Pittsburgh's 81 year old Mt. Washington tunnel has been made safe for many more decades of light-rail transit use, with the use of foamed chemical grout. The job is the first...
Unearthing Mt. Baker Tunnel
A new tunnel under Mt. Baker in Seattle is part of major improvements to I-90 between Bellevue and Seattle's business district. Feasibility studies began in 1963, but it was...
Tunnelling in Soil and Rock
The relationship between tunnel design and construction is covered with emphasis on case histories of field measurements and performance. A general report emphasizes the importance of...
Guidelines for Tunnel Lining Design
These guidelines set forth a program for conceptual and practical orientation in the design of tunnel linings. They are not intended to be used as a code or collection of specifications....
Tension Tests of Containment Wall Isolated Liner Plates
Two tests were conducted using an approximate 2:1 ratio of hoop to meridional load. This simple load ratio is a gross approximation of the liner plate loading in a containment subjected...
Structural Performance Predictions for Liner Plates on Nuclear Facilities
The history of the use of liner plates is presented. It is shown that the liner plate can be buckled, and can be bonded or not bonded to the concrete. The buckled plate usually has bending...
Containment Capability
Section 2. 0 of this report contains a description of analysis methods for the containment structure. Testing on containment models and sections of containments is described. Section 3....
Reliability-Based LRFD for Transmission Structures
A simple reliability-based Load and Resistance Factor Design (LRFD) method is proposed for the structural design of electric transmission lines. With the proposed method, the designer...
Selecting an Economical Water Main Rehab
Many miles of aging water mains exist with carrying capacities that are less than half of what they were when new. Engineers must, therefore, stretch every dollar to eliminate deposits...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
Guidelines for Transmission Line Structural Loading
Procedures are provided for the selection of design loads and load factors based on the latest research and state-of-the-art design techniques. This selection has an effort on the reliability...
EPA's New Land Disposal Rules�A Closer Look
Despite some initial enthusiasm for the new EPA regulations on land disposal of hazardous waste, many critics are now expressing concern for the long-term environmental impact. The dependence...
Lining a Pond to Contain Uranium Tailings
Impermeable pond linings combined with geotextile fabric underlinings are a recent innovation in industrial storage pond construction. A case history of a pond site in New Mexico illustrates...
Lining Tunnels: Toughest Concreting Job?
Concrete linings for water supply tunnels must resist sulphate and other chemical attack, not contribute pollutants to the water it is carrying, and not leak for its design life, which...
