Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...
Structural Analysis in Context
The issues of what student should learn about structural analysis and how it should be taught are explored considering the purposes of structural analysis in engineering practice and the...
Construction of CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) systems have been installed as overtopping protection on three small embankment dams along the Blue Ridge Parkway. Based on field tests by others and on the...
Prestwood Lake Dam Rehabilitation
The Prestwood Lake Dam located in Hartsville, South Carolina is owned by Sonoco Products Co. It originally was a wood structure built in 1895. That structure was washed out by a hurricane...
Remedial Works at Troneras and Miraflores Dams in Colombia
The 38 m high Troneras and the 55 m high Miraflores earth dams were built in the period 1959-1965. The dams are composed of residual soils and founded on a deep residual overburden. Significant...
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...
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...
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...
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...
MASSPORT Modernization
Construction began last fall on the Massachusetts Port Authority (MASSPORT) upgrade of the 50-year-old Paul W. Conley Terminal in Boston. When completed in 1994, this timber-pile-supported...
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...
Plastic Piling
Composite plastic and steel piles are gaining acceptance throughout the United States. The evolving technology has produced a unique product which solves several problems related to use...
