The vibration method of immersing sheet piles, piles and pipes in the Soviet Union was widespread in the postwar years. The initiative in the development of this method belongs to D. D. Barkan. Back in 1934 in the laboratory of the research Institute of Foundations of Structures experiments were conducted [5], during which for the … Continue reading Introduction
Editor's Note: in part as a follow-up to this post, I am putting up a translation of this chapter from the "seminal" classic on the subject of vibratory and impact-vibration pile driving. It is interesting to note that the lead designer on the original models of vibratories with both translational and rotational motion is M.G. … Continue reading Rotary Vibratory Hammers
For links to the rest of the book, click here. Editor's Note: this topic is sort of the "Holy Grail" of vibratory pile driving, and has certainly been studied since the publication of this book, mostly in Europe. The Soviet perspective on the problem is interesting. It is also interesting that they discuss the bearing … Continue reading Bearing Capacity of Piles Driven by Vibration Method and Manufactured Using Vibration Technology
To access the rest of the book, click here. Editor's Note: for the most part this concerns a topic that U.S. contractors would consider drilled shafts. (The term here is "filled piles;" the literal translation of the Russian term is "stuffed piles," which driven pile people might find amusing, but I thought it would be … Continue reading Manufacturing Piles Using Vibration Technology
For links to the rest of the book, click here. Work on the reconstruction of existing enterprises occupy a significant place in construction, and their volume is constantly increasing. This determines the need for building foundations near existing structures by high-performance methods, which include the vibration] method. It should be noted that in the conditions … Continue reading Application of the Vibration Method Near Existing Structures
In my recent post Dynamic Measurement of Piles the Case Method was brought up and outlined. The Case Method is one of the oldest methods developed to estimate the static capacity of piles from dynamic measurements. The method is detailed in the FHWA document Design and Construction of Driven Pile Foundations; this will serve as an … Continue reading The Case Method: An Overview and Worked Example
Editor's Note: This monograph was produced by Petro-Dynamics, Lafayette, LA. It was undated; it probably was produced in the early 1980's and was disseminated at the Offshore Technology Conference. Although it is around four decades old, the basic concepts of the Case Method and CAPWAP are still in use today. One thing that surprises is … Continue reading Dynamic Measurement of Piles
Don C. Warrington, PhD., P.E., University of Tennessee at ChattanoogaOrignal Date May 2011Revised September 2017 Methods of estimating the static capacity of driven pile are almost as numerous as the dynamic formulae of years past. As was the case with dynamic formulae, some have become embedded in codes, standards and the literature. All of these, … Continue reading The Dennis and Olson Method for Determining the Static Capacity of Driven Piles
For other parts of the book, visit Vibro-Engineering and the Technology of Piling and Boring Work. Editor’s Note: This is a reasonable summary at the time it was written (1987) as far as it goes. Already, however, the dominance of the Japanese was waning (one Russian trade representatives told me that the Japanese weren’t very good … Continue reading Status of Pile Vibration Equipment Abroad
You can access other parts of this book here: Vibro-Engineering and the Technology of Piling and Boring Work. Editor's Note This is a topic which was of great interest to Vulcan in the development of its vibratory pile drivers and extractors. As was the case with the Russians, all earlier vibratory drivers (including the Uraga units … Continue reading Means of Protection Against Vibrations of Load Lifting Devices Working With Vibration Exciters
