Comments on “A novel soil reaction model for continuous impact pile driving”

This is yet another paper which cited my work, in this case the ZWAVE paper. Once again I'm not sure why they picked this one; it's probably because I explored a soil model based on that of Randolph and Simons (1986), which they also cited and discussed. I came back to models like this in … Continue reading Comments on “A novel soil reaction model for continuous impact pile driving”

The Basics of Vibratory Power Theory

This is a brief summary of the basic theory behind vibratory power. It goes back to Savinov and Luskin (the original summary of the development of the technology) and I've covered it repeatedly in my monographs. The basic model is shown above. It assumes that that soil acts as a velocity-dependent damper, which speaks to … Continue reading The Basics of Vibratory Power Theory
