Avoiding Impacts of Collapsed Mines on Railways: A Multidisciplinary Geophysical Detective Approach
The presence of abandoned mine workings can pose a significant risk to the use and development of surface structures above them, including railway lines. Typically, the adverse and often sudden effects...

Design of the Future Mexico City Airport: Attaining Resilience in Soft Ground
The Lake Texcoco region to the east of Mexico City is famed for its deep lacustrine deposits of compressible clay, which amplify ground shaking during seismic events. The area is also gradually subsiding...

Calibration of Jackup Leg Foundation Model Using Full-Scale Structural Measurements
The fitness of jack-up rigs to operate in varying water depths and weather conditions is determined by "site-specific" structural assessments. These assessments are conducted by a wide range of companies...

A Preliminary Case for the Existence of Hurricane Alleys in the Gulf of Mexico
A review of hurricance intensity in the Gulf of Mexico suggests there are two alleys where hurricanes are roughly 20% more intense than elsewhere. This paper develops a physical basis for the alleys using...

Journal of Transportation Engineering, Part A: Systems
The Journal of Transportation Engineering, Part A: Systems contains technical and professional engineering articles on the planning, design, construction, operation, and maintenance of air, highway, rail,...

Rock Glue Gets the Job Done: Reducing Rockfall Hazards along the G.W. Parkway
After a large rockfall damaged the road and disrupted traffic along the George Washington Memorial Parkway in 2002, the National Park Service was looking for solutions to stabilize the slope against additional...

Photogrammetry for Rock Engineering: A Snapshot of State-of-the-Art Rock Mapping
Generally speaking, photogrammetry is the science of turning photographs into 3D models. While flashy advertisements may convey the idea that it's as simple as pushing a button (e.g., on a drone remote)...

Geotechnical Aspects of Pavements: There's More to Roads than Asphalt and Concrete!
When you jump on the highway to make that commute to work, do you think much about what's under the surface you ride on? Pavements are layered systems designed to provide a strong structure to support...

Extreme Makeover: Interchange Gets Ground Improvement Facelift
As part of the massive, $159.9 million Interchange 14A Improvement Project in the cities of Bayonne and Jersey City, NJ, the New Jersey Turnpike Authority (NJTA) is realigning 12 ramps and roadways and...

Making Big Data Work for You and Your Project: A 3-D Geotechnical Model is a Smart Way to Work
Modeling the stratigraphy beneath a site and assigning soil and rock properties are important steps in geotechnical engineering. Geotechnical engineers often need to model ground conditions...

BIM in Geotechnics: The Benefits of Including Geotechnical Data in Building Information Modelling
Building Information Modelling (BIM) is becoming increasingly common around the world on building and civil engineering projects, but what are the benefits to geotechnical engineers and...

Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...
