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,...
Bring Your A-GaME! and Dominate the Field [Investigation] � As Newer Technologies Mature and Are Adopted More Widely � It�s A Whole New Ball Game Out There
The Federal Highway Administration (FHWA), in collaboration with industry partners, is helping state DOTs take their existing geotechnical site characterization programs to the next level. Technologies...
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,...
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...
Swarms of "Stormquakes" Identified for First Time
Test Your Soil Models Against the Case Data Base
Tall Building Seismic Safety Report Released
Purdue University Tests Use of Large Open-Ended Pipe Piles on Indiana Bridge
Seismic Design
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...
Permeable Pavement Research Needs
The implementation of permeable pavement installations and practices are expanding and becoming more commonplace. With this increased usage comes expanded and improved information on design,...
General
Design of Latticed Steel Transmission Structures specifies requirements for the design, fabrication, and testing of members and connections for electrical transmission structures. These...
Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
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...
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...
Axial Load Capacity of Pipe Piles in Sands
The axial load capacity of driven, open-ended, steel pipe piles in cohesionless soils, is often estimated using a method such as the American Petroleum Institute Recommended Practice 2A...
Shear and Interface Strength of Clay at Very Low Effective Stress
Thin-specimen direct shear (TSDS) tests were conducted to measure the shearing strength of kaolinite, and interface strengths between kaolinite and acrylic plastic and anodized aluminum,...
Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...
Pile-Driving Formulas for Friction Piles in Sand
Dynamic pile-driving formulas are widely used in predicting the load-carrying capacity of friction piles and in writing pile-driving specifications. Further, when load tests are available,...
