For the rest of the book, click here. The significant complexity of the phenomenon of vibrational immersion of bodies into the ground and the difficulties associated in choosing the optimal parameters of pile vibratory drivers prompted many researchers to attempt to construct a theory of vibrational immersion and vibroextraction. Work on the creation of such … Continue reading Existing Proposals for the Theory of Vibratory Pile Driving
Factors on which the speed and depth of immersion of a pile subjected to vibration depend
For the rest of the book, click here. The main factors that determine the process of immersion in the ground (or extraction from the ground) of a pile subjected to vibration are the intensity of vibrations and the value of the resultant of external statically acting forces applied to the pile. Consider the influence of … Continue reading Factors on which the speed and depth of immersion of a pile subjected to vibration depend

In a form accessible to the engineer, this book outlines the basics of theory, technology and experience production application of the vibration … Continue reading The Vibration Method of Driving Piles and Its Use in Construction
Physical and Mechanical Features of the Phenomenon of Vibration Immersion
Immersion in the ground of bodies subjected to vibration represents a complex mechanical phenomenon. Let us consider the features playing the most significant role in the process of vibration immersions so you can correctly understand the mechanism of this process. Imagine that at the head of a pile immersed in the ground to a certain … Continue reading Physical and Mechanical Features of the Phenomenon of Vibration Immersion
Introduction
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
Rotary Vibratory Hammers
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
Bearing Capacity of Piles Driven by Vibration Method and Manufactured Using Vibration Technology
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
Manufacturing Piles 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
Application of the Vibration Method Near Existing Structures
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
The Case Method: An Overview and Worked Example
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
