Intergalactic Soil Nails: Excavation Support for the Deep Space Auditorium
A software company based outside Madison, Wis., had a need for an auditorium as part of its campus expansion in 2011. The 829,000-sq-ft, 11,400-seat "Deep Space" auditorium was to be built underground,...
Your Numerical Model Begins at the Site Investigation � Phase Improving the Suitability of Numerical Geotechnical Modeling
The success of an advanced geotechnical numerical analysis depends foremost on a thorough geologic and geotechnical understanding of the site, and thus the geometric definition and adequacy of input parameters...
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...
What�ll They Think of Next? Dewatering Contaminated Slurries Using Geotextile Tubes
Sediment must be dredged from the bottom of waterbodies to maintain their capacity and navigability. Dredging, by its nature, involves the removal of highwater-content slurries and also helps preserve...
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...
Design of Shoreline Protection Measures : The Importance of Geotechnical Engineering in Waterfront Design
Over the past decade, there�s been an increased realization of the need to better protect our shorelines, particularly in urban environments along coastlines that have already been impacted by storm surge...
Beyond the Water�s Edge: Geotechnics in the Wet
Gaining insight into the subsurface and developing an understanding of what�s hidden below ground is a key to the design and construction process. Geotechnical engineers and geologists often develop their...
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...
