Liquefaction Potential Leads to Dam Reconstruction
Results of a visual inspection of the Dundee Dam conducted in 1982 revealed the presence of seepage on the downstream toe of the left embankment. Subsequent subsurface explorations and...
Using Innovative Technologies and Geosynthetics in Embankment Dam Rehabilitations
The ever increasing development and confidence in new and innovative technologies such as geosynthetics, in conjunction with often significant economic advantages, have led designers to...
Construction and Verification of Ground Improvements at Mormon Island Auxiliary Dam
Mormon Island Auxiliary Dam, part of the Folsom Dam and Reservoir Project near Sacramento, California, is founded on alluvial materials that were dredged and processed for gold on several...
Rehabilitation of the Deep Creek Lake Dam
This paper presents the rehabilitation design for upgrading the Deep Creek Lake dam. The Deep Creek dam is a rock fill dam, 92 feet (28 m) high and 1290 feet (393 m) long, and constructed...
Trial Lake Dam Reconstruction
Trial Lake Dam is located in the Uinta National Forest in Central Utah at an elevation of about 10,000 feet. The dam is 50 feet high and stores 1,700 acre-feet of water for downstream...
Seismic Safety Modification of an Old Earthfill Dam
Chollas Dam was built as a water supply reservoir for the City of San Diego. The reservoir is no longer a part of the municipal water system but has been operated since 1966 as a recreational...
Hydration Properties of Shotcrete with an Accelerator Based on Calcium Aluminate
A new powder-type accelerator based on calcium aluminate has been used for shotcrete in underground construction. This accelerator can be applied to all types of shotcreting. The shotcrete...
Design of Tunnel Lining from Shotcrete in Combination with Anchors
The method of designing tunnel linings from shotcrete in combination with anchors is given in the paper. The method is based upon the solution of the plane contact problem for a double-layer...
Single-Shell Shotcrete Method
On a 60-m-long test stretch in the course of the construction of the Munich Subway the single-shell jointless shotcrete method was employed. In this case the standard cross section of...
Two Shotcrete Lined Tunnels in the United Kingdom
The paper describes two large diameter tunnels recently built in southern England where shotcrete has been used as the primary support. The design methodology is described together with...
Lattice Girders for Shotcrete Support
Lattice Girders complement the use of shotcrete for underground support by reducing the risk involved with using shotcrete alone for temporary or permanent lining of a tunnel or shaft....
Recycled Roads
The movement to recycle wastes in highways appears to be gathering momentum nationwide. Rubber from old tires, wood chips, reclaimed asphalt pavement, fly ash, scrap plastic, mining wastes...
Driving Under a Construction Site
Throughout the summer of 1992, vehicles passed unimpeded through one of the most heavily traveled intersections in Los Angeles County as construction proceeded on a concrete light-rail...
Supply-Side Solutions
Although the crumbling bridge infrastructure has received much attention in the press and the engineering community over the past few years, the number of structurally deficient bridges...
What Do You Mean by That?
The engineering and construction profession, like any other, has its own buzzwords and jargon. But as terms become ingrained in the profession's lexicon, they take on different...
The Long Term Interim Storage of Spent AGR Fuel
This paper describes the work undertaken by Scottish Nuclear Ltd. on the proposal to construct a naturally cooled dry store for spent advanced gas cooled reactor fuel at Tornes Power Station,...
Hanford Waste Vitrification Project Overview and Status
The Hanford Waste Vitrification Project (HWVP) is being constructed at the U.S. Department of Energy's Hanford Site in Richland, Washington. The paper gives an overview of the HWVP which...
Selection of the Initial Access for the Yucca Mountain Exploratory Studies Facility
This paper describes the activities undertaken to examine relevant factors and select the initial access for the Yucca Mountain exploratory studies facility. To aid their decision, the...
Installation and Routing of Critical Embedments at the Hanford Waste Vitrification Plant
During the preliminary design phase of the project, a study was conducted to develop concepts for routing embedded piping and conduit between the remote cells and the service corridors...
Glass Melter Assembly for the Hanford Waste Vitrification Plant
The Hanford Waste Vitrification Plant (HWVP) is designed to solidify high level radioactive waste by converting it into stable borosilicate glass after mixing with glass frit and water....
