Turnback Project Moves Ahead
The $202 million Muni Metro Turnback (MMT) Project, scheduled for completion in September 1996, includes an 840 ft section consisting of twin steel-lined tunnels that connects to the Embarcadero...
Blasting Densifies Volcanic Debris (Available only in
The relatively new ground improvement technology of blast densification overcame soil problems posed by volcanic ash at Mount St. Helens National Volcanic Monument. In 1993 WSDOT began...
Start the Presses!
Turning an existing bleach manufacturing facility into a printing plant required careful structural design to support a wide range of production processes. The new Daily News facility...
Scour around Exposed Pile Foundations
Laboratory experiments were conducted to measure local scour around exposed pile groups for a variety of conditions including different spacings, different skew angles, different patterns...
Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...
Defect Detection (Available only in Geo/Environmental Special Issue)
Sonic integrity logging technology can detect flaws in deep foundations more reliably and at less cost than conventional boring techniques. These non-destructive test tools are being used...
Pile Wall Cuts Off Seepage (Available only in Geo/Environmental Special Issue)
An unusual cutoff wall constructed by the secant pile method succeeded in drying up seepage through the permeable strata below a saddle dam at Beaver Dam in Arkansas, owned by the U.S....
Chicago's Micropile Debut
On a tight, urban site around Chicago's historic Orchestra Hall, engineers used high-capacity micropiles as an alternative to hand-dug caissons. On a $104 million project...
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...
Singapore Showcase
A new bridge in Singapore has a unique pylon design and no piers. The deck hangs from the pylon supported by three back stays. The 100 m overpass bridge was designed for the Singapore...
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...
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...

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...
In the Wet
The concept of using large diameter vertical cylinder piles of steel and concrete is not new. Vertical cylinders constructed in pneumatic caissons go back at least 70 years. Steel cylinders...
Bridge Design: Reality Bites Back
Many bridge engineers tend to ignore the process nature of reality, the fact that everything in this universe changes from moment to moment. When they are given the responsibility for...
Engineering a Landslide
A slope failure in northwest Alabama has been stabilized using a system of grouted INSERT piles to provide load transfer across the failure surface of the slide. This system, referred...
Foundation Upgrading and Repair for Infrastructure Improvement
This proceedings,
A Primer on Micropiles
A major study of micropile technology has recently been funded by the Federal Highway Authority and completed by the authors. The subject is defined as a drilled and grouted, cast-in-place,...
Monitoring of Structures During Repair of Underground Utilities
A collapse of underground utilities at a power plant required the constant monitoring of the surrounding structures during excavation and replacement of the damaged pipes. A computer-based...
High-Strain Kinetic Testing of Deep Foundations
High-strain kinetic testing involves the upward decelerating or accelerating of a mass and using its inertial force to axial prolonged pulse at the head of a pile. Currently available...
