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
Click here to view the home page for the book. The use of vibration technology allows: increase labor productivity while saving energy and material resources; use mobile means of vibration technology and use them without bulky support structures for the perception of reactive forces; complex mechanization of construction processes. Table 1 lists the types of … Continue reading Application of Vibration Technology
Click here to view the home page for the book. The theory of vibrational and impact-vibrational immersion is connected with the study of essentially non-linear systems, in which the nonlinearity is determined both by the forces of resistance (for example, when studying longitudinal-rotational vibrations) and by the dynamics of the vibration exciter itself, for example, … Continue reading Basics Of The Theory Of Vibratory Immersion and Extraction
The rest of the book can be found here. Analyzing the data given in § 1 and 2, the effect of the interaction of the vibrating body with the ground can be explained as follows. During vibrational immersion of elements into the ground, by introducing additional sign-alternating forces and/or torques, it is possible to significantly … Continue reading Scope of Effective Application of the Vibration Method and Classification of Vibration Machines
For the rest of the book, click here. During the experimental study of the process of vibro-driven piles (O. A. Savinov, A. Ya. Luskin, M. G. Tseitlin, S. V. Plekhanova, 1954; N. A. Preobrazhenskaya, 1958; D. D. Barkan, 1959) and analysis of the results of studies of the lateral and frontal soil resistance (I. I. … Continue reading Calculation Models of the Interaction of an Immersed (Extracted) Element With the Soil
For other parts of the book, click here. Experimental data on the processes of vibro-driving and vibro-extracting were obtained for the first time by D. D. Barkan, who established the possibility of a significant decrease in the constant force required to drive a pile or extract it, in the case when the pile makes longitudinal … Continue reading The Essence of the Processes of Vibrational Immersion and Extraction. Interaction of Vibrating Bodies With Soil.
I recently wrote a paper entitled Development of a Parametric Model for the Simulation of Impact-Vibration Pile Driving Equipment. It was presented earlier today at the 2023 Spring Research and Arts Conference; the slide show for the talk is here. One of the impact-vibration hammers featured--probably the "cleanest" one in terms of the results--is the … Continue reading The S-402A Impact-Vibration Hammer
