Some Lessons from “Savinov and Luskin”

by Don Warrington, posted in Drivability and Vulcan Hammers, Vulcan and Vibratory Hammers

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. For more information on the impact-vibration hammers, click here. When carrying out excavation work in winter or in permafrost conditions, the most labor-intensive and expensive operation is the loosening (preliminary destruction) of frozen soil. This operation is performed using various mechanisms and devices. All of them have … Continue reading Application of Vibratory Hammers in the Development of Frozen Soils
