Compensation Grouting
To minimize ground movement while tunneling a sewer 5 m below Toronto's Spadina subway line, engineers used special instrumentation, tunneling control and grouting to limit...
Putting On Your Safety Cap
Geomembranes are an important part of landfill cap design. However not all geomembrane liners are created equal, and it's best to know what a liner is made of before specifying...
Dam Engineers Go Over the Top
In the 1980s, dam engineers with the Lower Colorado River Authority worried that the Wirtz Dam, near Austin, Texas, would fail in the event of a maximum probable flood. They looked to...
Monumental Restorations
Modern nondestructive field surveys and state-of-the-art static dynamic monitoring systems provide important information for historical renovations while ensuring that the structure remains...
On Solid Ground (Available only in the Geoenvironmental Special Issue)
On four transportation projects in Portland, Ore., soil nails and micropiles are used as alternatives to conventional earth-retention and foundation systems. The use of soil nails and...
Mapping with a Differential
A southern New Jersey landfill is using Differential Global Positioning System topographic surveying to cut costs and turnaround time on annual mapping and volume certification. Modern...
Hydraulic Fracturing Advances (Available Only in Geoenvironmental Special Issue)
Removing contaminants trapped in clays and nonpermeable soils can be difficult if not impossible with traditional extraction methods. A look at four hydraulic fracturing case studies shows...
Containing Contaminants (Available Only in Geoenvironmental Special Issue)
The Environmental Protection Agency and the Department of Energy are currently in favor of containing contaminants and either remediating on site or simply capping such materials within...
Artificial Neural Networks for Civil Engineers
Fundamentals and Applications
Sponsored by the Committee on Expert Systems and Artificial Intelligence of the Technical Council on Computer Practices of ASCE. This report describes...
Bump At the End of the Bridge
Interface bumps between bridge abutments and embankments increase risk and add over $100 million to maintenance expenses every year. New research reveals effective ways to deal with the...
Fathoming the Strength of Structures
More and more, the owners of bridges and piers are budgeting rehabilitations based on inspections done underneath the waterline. Increasingly, they want the underwater inspectors to be...
The Evolution of Geosynthetics
Although the geosynthetics industry only began in the 1960s, it roots can be traced to the earliest humans. Soil stabilization, soil reinforcement, liquid drainage and leak proof barrier...
Preparing for Repair (Available only in Geoenvironmental Special Issue)
The Sacramento River Water Treatment Plant, Sacramento, Calif., was built in 1924 and hadn't been upgraded since 1958. In 1996, the city of Sacramento, the owner of the plant,...
