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...

Learning From Pile Driving Failures: Out of Sight Can't be Out of Mind
The design of driven pile foundations for static service and strength limit state loading conditions is meaningless if the piles cannot be driven to the required depth and nominal resistance without sustaining...

In the Wake of the Mount Polley Mine Tailings Breach: Tailings Dam Design, Innovation, and Practice Changes
The Mount Polley tailings dam in British Columbia (BC), Canada, failed in 2014, spilling approximately 21 million m3 of water and tailings (estimated as approximately 50/50 water and tailings) into Hazeltine...

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...

Advanced Data Analytics In Geotechnics: Adapting to the Big Data Era
Everyone is talking about the impact of artificial intelligence (AI) on the future of work. In one camp are people like the industrialist Elon Musk who fear the potential evils of AI and its possible impact...

Seeing into the Subsurface: Harnessing Geophysics to Remotely Monitor the Condition of Earthworks
Condition assessment of geotechnical structures is essential for cost-effective maintenance and prevention of hazardous failure events. Early identification of deteriorating conditions generally allows...

Soil Sampling at Sword Beach in Normandy, France, 1943: How Geotechnical Engineering Influenced the D-Day Invasion
When the World paused last summer to remember the 75th anniversary of D-Day, many of us were gripped by stories, both heroic and horrific, told about the Allied invasion of Normandy’s beaches. One of these...

Tsunami Loads and Effects
