As mentioned earlier, it would be a long business to catalog all of the methods that have been devised to estimate the axial bearing capacity (with all of the problems of that concept) of driven piles. Here we will show how three of these methods apply to our test case (reproduced below.) More Resources Foundation … Continue reading Driven Pile Design: Three Methods of Analysis
More Resources Foundation Design and Analysis: Deep Foundations, Driven Pile Bearing Capacity Design and Construction of Driven Pile Foundations, 2016 Edition, Volume I covers the topics discussed in this post. Before I get into the actual estimation (and estimation is the operative word here) of axial capacity, I need to make some important observations, as … Continue reading Driven Pile Design: Axial Loads, General Considerations
Another view of Santa Fe's Vulcan 560 at work. This wasn't the ideal way to lean the hammer, but one of the things that make Vulcan hammers popular was their ability to perform when misused or mishandled. The design of driven pile foundations--the oldest form of deep foundation in use--is something that gets the short … Continue reading Driven Pile Design: Introduction and Overview
Sheet pile walls are deceptively simple retaining walls to analyse. Because a) the loads are generally distributed and b) the layering of the soil is complex, a simple problem can turn into a complicated one very rapidly. An outline of the hand solution method for cantilever walls is shown below. That's why today software such … Continue reading Designing Cantilever Sheet Pile Walls Using a Chart
The discontinuation of the TAMWAVE wave equation program has left something of a void in our offerings. This post explores the alternatives that we have on hand, primarily for educational purposes. (All offerings of this site are subject to the Terms and Conditions of This Site.) The Problems When the first geotechnical site of this family … Continue reading The Wave Equation after TAMWAVE: Alternatives and Substitutes
It is with great regret that the discontinuation of our "active pages" is announced. By "active pages" we mean the software that was designed for use in a web browser. With the migration of the "vulcanhammer" family of sites it is not possible to host these here, and changes in the hosting service have made … Continue reading The Discontinuation of Our Active Pages, and the Substitutes
This paper is scheduled to be presented today at the Spring Research and Arts Conference at the University of Tennessee at Chattanooga. The presentation slides for this paper (with its abstract) can be found here. The paper itself is here.
One of the mysteries of geotechnical engineering relative to driven piles is why the Soviets, with their mathematical prowess, never applied wave mechanics to predict the performance of pile driving systems using the wave equation. In a sense this book, which is a classic in the geotechnical literature, answers that, but not in a direct … Continue reading Some Lessons from “Savinov and Luskin”
For the rest of the book, click here. I debated whether to translate the reference section. I ended up deciding not to do so. Most all of the material referenced in this book is in Russian and my guess is that most of it has never been translated into another language. So what I have … Continue reading References
For the rest of the book, click here. The resolution of the June plenum of the CPSU Central Committee emphasizes the need, when developing and implementing new technological processes and machines, to proceed from the point that they meet the requirements of the most rational and economical use of social labor, material and monetary resources, … Continue reading Conclusion
