Street Smarts
Sensors, cameras, and other technologies are helping cities monitor and manage their streets better. Data from such "smart streets" are enabling engineers and other transportation experts to improve safety...

Creating Art AND Reducing Project Risk WITH 3D Modeling: Digital Insights Unearth Hidden Landscapes
Humans have always lived in threedimensional space, with senses that evolved for a 3D environment. So, it’s perfectly natural that people can more quickly, easily, and fully understand something when it’s...

Highway Embankment Failure on Soft Clay: Bad Input = Bad Output
Our ability to analyze and compute 2D and 3D factors of safety for embankments and slopes, including finite element and finite difference analyses, has increased greatly in the last decade. However, use...

Flexible Rockfall Barrier Post Support Performance: Deflection as a Positive Attribute
Rockfall has plagued infrastructure for centuries, whether generated by natural weathering of unaltered rock slopes or due to jointing and weaknesses in constructed rock slopes. Rockfall in the U.S. has...

Automated Model And Parameter Selection: Incorporating Expert Input into Geotechnical Analyses
Excavation for construction of MIT Stata Center in Cambridge, MA. This complex soil-structure interaction problem required advanced numerical methods and soil constitutive models. A) PLAXIS 3D model of...

Technology Briefs: 3-D Printers Build Model Cities for Wind-Tunnel Tests

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)...

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...

Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...

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...

Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...

Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...
