When AI Meets DIGGS � The Birth of a New Site Characterization Paradigm?
Drilling and sampling to obtain borehole logs, together with various in-situ testing, are usually performed to determine subsurface soil and rock profiles and their associated engineering properties. However,...
Practical Aspects Of Routine Geotechnical Site Investigations � They Should Be Anything But Boring!
It�s likely that on any given day there are hundreds of geotechnical site investigations in progress in North America alone. While many of these investigations are carried out in support of large projects,...
Moving Down the Road of Progress: Geosynthetics Subdue Failures on Expansive Clays and Frost-susceptible Soils
Using geosynthetics in roadway projects has provided sustainable alternatives for reconstruction and maintenance and now represents a significant portion of the total geosynthetics market. Geosynthetics...
Sediment Pollution: Solving "Rill" Problems Using RECPs
Sediment pollution causes an estimated $16 billion in environmental damage annually. Sediment is the most common pollutant in rivers, streams, lakes, and reservoirs, causing such negative effects as temperature...
70 Years of Soil-Bentonite Slurry Walls: So, What's New
The soil-bentonite slurry wall (SBSW) is an established ground improvement technology that continues to find applications. It�s often the best and most economical vertical barrier to essentially stop lateral...
A Brief History of Jet Grouting in the Last 50 Years: The Story of Its Evolution
Jet grouting, a grouting soil improvement construction technique, was first developed in Japan in the 1960s and 1970s, and then introduced in Europe a few years later in the form of a proposal for soil...
Working Platforms for Specialty Geo-Construction
A major cause of rigs toppling over is the state of the "working platform" that they must work from. A working platform is a layer of material, often compacted sand or gravel, placed over the subgrade,...
Years of Planning for the South San Francisco Bay Shoreline Project: Now It�s Time to Build! Rapidly but Gently!
When a complicated project is completed, and you ask the engineers, "What was the most challenging part of this project?" a couple of difficulties usually come to mind. We�ve all heard war stories from...
Seismic Performance of a Deep Soil Mixing Grid: A Magnitude 7.1 Load Test at the Port of Alaska
The Port of Alaska in Anchorage (Port) has embarked on a multiphase modernization program that includes the development of a new petroleum and cement terminal (PCT) berth. The berth consists of a pile-supported...
Megaproject Monitoring by Satellite ? InSAR-based Settlement-time History: Measuring Hundreds of Thousands of Points, Several Times a Month, Across an Entire City
Satellite-based interferometric synthetic aperture radar, or InSAR, has gained unequivocal importance as a routine and precise monitoring method for large and small areas alike. Historical datasets allow...
Risk in Geotechnical Practice: Geotechnical Judgment
People use judgment in every aspect of their lives. We rely on our judgments to make decisions that can have consequences from small to large on ourselves and on others, sometimes with life-threatening...
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...
Tsunami Loads and Effects
Guide to the Tsunami Design Provisions of ASCE 7-16
The devastating tsunamis that struck Chile and Japan in 2010 and 2011 underscored the critical need for new structural design criteria to improve building resilience and safeguard human life. They also...
Poison Oak, Mistakes, and Lessons
When things go wrong in geotechnicalengineering ? like ground movements andearthwork construction delays ? failureinvestigations are often performed. In a typical geotechnical project, the path is relatively...
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,...
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...
Geotechnical Risk Management: The Five Non-Technical Topics that are Crucial for the Successful Practice of Geotechnical Engineering
It is fair to state that the aspects of civil design and construction referred to as geotechnical engineering can be characterized as inherently risky. Geologic processes are complex,...
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...
