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...

Performance-Based Earthquake Engineering: What Can It Do for You?
There's been a lot of talk, and some confusion, lately about performance-based earthquake engineering (PBEE). Many geotechnical engineers wonder -- what is it, how does it differ from what I've been doing,...

Ground Feature Monitoring Using Satellite Imagery: How Interferometric Stacking of SAR Can Mitigate Geo-Disasters Along Transportation Corridors
Landslides, debris flows, and other types of ground movements are among the most common hazards to humans and infrastructure. According to the United States Geological Survey, annual domestic...

Detailed Site Investigations
This section addresses site investigation issues that are important for detailed design and construction of microtunneling projects. These site investigations include the following: Geotechnical...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Extreme Wave-Force Calculation Procedure for 20th Edition of API RP-2A
The paper describes the revised guideline design wave force calculation procedure approved for the 20th edition of the API-RP2A WSD and the first edition of the API-RP2A LRFD and contrasts...

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...

Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...

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 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...

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...

Reliability and Resilience — Essential Ingredients of Sustainable Geotechnics
Sustainability of a system is its ability to survive and retain its functionality over time. In very simple terms, sustainability deals with the capacities (resistances) and demands (loads)...
