Optimized Drilled Shaft Design through Post-Grouting: Shorten That Shaft for Better Performance
Tip post-grouting is a technique used to inject, under pressure, a neat cement grout beneath the base of a drilled shaft. This method enhances or improves axial load-displacement performance by increasing...

Spread Footings Revisited: Geotechnical Advances Lead to Expanded Use for Bridge Abutments
The Minnesota Department of Transportation (MnDOT) has historically used steel shell piles to support highway bridge structures, probably due to a blend of familiarity and efficiency among...

Screw Piles and Helical Anchors: 180 Years of Use in Geotechnical Engineering
Since 1836, screw piles and screw cylinders have been used successfully throughout the world to support a variety of large-scale, civil engineering structures. Their development and use...

Long-Term Performance Monitoring of a Hillside Retaining Wall
To accommodate expansion of the West Point Treatment Plant in Seattle, WA, a 3,000-ft-long soldier pile, tieback-anchored retaining wall was constructed from May 1991 to May 1992. An oblique...

A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...

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...

Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...

Finite Difference Analyses for Sand Drain Problems
The geotechnical literature contains a number of papers in which sand drain installations are described and field performance is compared with theoretical predictions. Some of the field...

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,...

Axial Capacity of Steel Pipe Piles in Clay
Development of theories for the prediction of the axial compressive and tensile load capacities of driven piles is made difficult by a variety of factors, e.g., disturbance of the soil...

Offshore Technology in Civil Engineering
Hall of Fame Papers from the Early Years
Prepared by the Program Committee of the Offshore Technology Conference of the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This series presents...

Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...
