Optimized Drilled Shaft Design through Post-Grouting: Shorten That Shaft for Better Performance
Tip post-grouting is a technique used to inject, under pressure, a neat cement grout beneath the base of a drilled shaft. This method enhances or improves axial load-displacement performance by increasing...

The Evolution of Launched Soil Nails
A 30-Year Retrospective
Launched soil nails are a unique remedial technology in the geotechnical construction toolbox. These 20-ft-long, 1.5-in.-diameter nails are installed in a single shot using a compressed air "cannon" at...

Geomechanical Model for Rock Foundation Settlement

Rapid Prototyping of Computer Models to Characterize Discontinuous Rock Masses

Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...

Power Shift
Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs....

Heat and Mass Transport in Porous Media

Dam within a Dam
A routine inspection of the Rock Run Dam, an 84-year-old Ambursen-type structure in Chester County, Pennsylvania, revealed major stress cracks and water stains on the inside face of the...

Highly Deformable Shotcrete Lining—Design and Experience

Load Transfer Behavior of Soil-Cement Columns in Soft Ground

Weighing Anchors
Modern anchorage systems offer design engineers and contractors unprecedented choice in load transfer mechanisms. Some anchors are highly specialized, while others are appropriate for...

Bridging Substance with Style
Engineers used an elegant form to come up with a functional solution when designing the new Damen Avenue Arch in Chicago. Two steel ribs, created using heat induction bending, closely...
