Tailings Dam Engineer of Record (EoR): There's Nothing Conventional About It
Engineer of Record (EoR) is a simple and resolute concept that's applied throughout the western world for civil works construction. It's a term that fits in a nice neat box; it represents a single person...

Tailings Impoundment Closure: It's All in the Eye of the Beholder
Since the early 1900s, the mining and power-generation industries have disposed of tailings and other waste products using impoundments. The term "tailings" typically refers to the fine-grained waste product...

ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part A: Civil Engineering
The journal will meet the needs of the researchers and engineers to address risk, disaster and failure-related challenges due to many sources and types of uncertainty in planning, design, analysis, construction,...

Remote Sensing: A New Revolution in Geotechnical Engineering
Remote sensing in the form of satellite imagery has become part of our everyday life—from displaying boring locations at a job site to the various mapping apps on our smart phones that help us get there....

Nature Sides with the Hidden Flaw: Lessons Learned from Failures of Earth-Support Systems
In recent years, the demand for excavations and fills of significant height has increased due to many factors, including requirements for below-grade parking for urban buildings and the need to construct...

Emergency Retaining Wall Replacement: The East 26th Street Slide Repair in Baltimore, MD
During a record rainfall on April 30, 2014, a century-old, stone retaining wall between a dense urban roadway (26th Street) and the CSXT railroad track in Baltimore, MD, failed. The stone retaining wall...

Post-Earthquake Reconnaissance Using Digital Imagery: A Bird's-Eye View
Over the last decade, remote sensing has played an increasing role in geotechnical earthquake reconnaissance through the use of satellite imagery, LIDAR, and unmanned aerial vehicles (UAVs). These techniques...

The 2010-2011 Canterbury, New Zealand, Earthquake Sequence: Impetus for Rethinking the Way We Evaluate and Mitigate Liquefaction
Liquefaction is a common cause of ground failure during earthquakes and is directly responsible for tremendous damage to infrastructure. Evidence of the impact of liquefaction includes failure of bridge...

Dry Dams and the Dayton Flood of 1913: The Origins of Integrated Systems Engineering Concepts
This article examines the history of integrated flood protection with particular focus on the 1913 Dayton Flood....

Small Projects are Big Deals
Geotechnical engineers work on a wide array of projects, ranging from small retaining walls or pavement projects, to construction of dams, canals, and foundations for bridges and high-rise...

A Light in the Deep: The Future of Offshore Site Investigations
For deep-water energy developments, hazard identification and risk assessments (that is, assessing the probability of occurrence along with the consequences of failure) are more important...

Evaluating Bridges With Unknown Foundations for Susceptibility to Scour: North Carolina Applies Risk-Based Guidelines to Over 3,750 Bridges
Scour occurs when flowing water removes erodible material such as sand and rock. For bridges over water, scour affects the stability of pier and abutment foundations and contributes to...

Achieving Success and Avoiding Failures with Permeable Pavements
This chapter provides experienced-based recommendations on how to achieve success with permeable pavements. This information is based on an informational survey completed by designers,...

Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...

Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...

Failure of a Large Circular Excavation
A circular excavation, 117 feet (36 m) in diameter by 90 feet (27 m) deep, was designed by an experienced engineering firm and construction was performed by an experienced contractor....

Failure of a Twenty-Foot High Retaining Wall
A cantilever retaining wall, designed in apparent accord with provisions in a civil engineering handbook, failed soon after construction. Analyses of the causes of the failure are presented....

The Best Surprise is No Surprise: The Geotechnical Engineer's Ethical Responsibility to Say No to Bidding
The subsurface characterization work that a geotechnical engineer must perform is critical to the success of every project that requires the cooperation of the ground, regardless of whether...
