Soft Ground Improvement in Lowland and Other Environments
The presence of thick deposits of soft clay combined with the effects of ground subsidence cause problems for engineering constructions for lowland areas such as the Central Plain (Chao...
Do-Nothing Cleanups
Restoring polluted soil and ground water to pristine condition is, in some cases, neither cost-effective nor feasible. So what's the best way to close these sites with minimal...
Soft-Ground Subway Construction
With its 89.5 route-mile system up and running, the Washington Metropolitan Transit Authority (WMATA) is now completing the $640 million Mid-City E Route. The new line presented formidable...
Nailing A Landslide (Available only in the Geo/Environmental Special Issue)
When mud flows in California threatened to stop traffic on a freeway and erode a street from below, Caltrans worked around the clock to stabilize the slope using soil nailing and shotcrete....
Asphalt-Concrete Water Barriers for Embankment Dams
Because of its simplicity in design and construction, the asphalt concrete core is rapidly becoming the water barrier of choice for embankment dams in many parts of the world. This is...
Design of Sheet Pile Walls
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 15 From foundation exploration and testing procedures...
Design with Residual Materials
Geotechnical and Construction Considerations
Residual materials are in-place soil and rock like material derived from the chemical weathering of rock. The nature of residual material is a function of the type of parent material and...
Engineered Contaminated Soils and Interaction of Soil Geomembranes
Due to liability issues, landfills are no longer considered the best method of waste disposal. Innovative, safe disposal methods for large quantities of contaminated soils and waste are...
Measuring and Modeling Time Dependent Soil Behavior
This proceedings presents a series of papers on both laboratory and field investigations, as well as constitutive modeling efforts, that all deal with the time dependence of soils and...
Non-Aqueous Phase Liquids (NAPLs) in Subsurface Environment
Assessment and Remediation
The growing number of incidents of soil and groundwater contamination with non-aqueous phase liquids (NAPLs) has caught the nation unprepared. A number of challenges confronted the three...
Earth Reinforcement and Soil Structures
Few subjects in recent years have raised the general interest and imagination of the Civil Engineering profession as the concept of reinforcing soil. The basic simplicity of the principles...
Detecting Leaks Electronically (Available only in Geo/Environmental Engineering Special Issue)
An innovative monitoring system originally developed to detect cyanide leaks at gold mines can now monitor the integrity of geosynthetic liners at municipal- and hazardous-waste landfills...
Boston Blockbuster
The Central Artery/Tunnel project in Boston is probably the single largest publicly-funded transportation project in the country at present. The total cost will be between $8 and $10 billion...
The Return of Deep Soil Mixing
Deep soil mixing, a technique originally developed in the U.S. in the 1970s but virtually ignored because for cost reasons, is regaining acceptance here due in large part to mechanical...
Residual Benefits
Stringent pretreatment and effluent standards and a lack of capacity prohibit their release into sanitary sewer systems. Landfill disposal is costly. The National Pollutant Discharge Elimination...
Touchdown for O-Cell Test
The Los Angeles Memorial Coliseum was badly damaged by the Northridge earthquake. There was seven months to complete 3 years of work to be ready in time for football season. The project...
Soft Ground Not Easy Ground for TBM
The King County Department of Metropolitan Services (formerly called Metro), faced with the need to transfer wastewater from the West Seattle drainage basin to a secondary treatment plant...
Partnering with the Enemy
When you think of EPA and a major corporation, you probably envision them squaring off in court over a Superfund site. But these days representatives from the two groups are just as likely...
Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...
Geoenvironment 2000
Characterization, Containment, Remediation, and Performance in Environmental Geotechnics
The impact of rapid industrialization around the globe and unsafe waste management practices have become increasingly significant within the last two decades as the disclosed number of...
