Lecture
This lecture covers the development of pile driving formulas, emphasizing the relationship between pile driving resistance and capacity. Various formulas are discussed, highlighting the importance of using simple formulas consistently for accurate comparisons. The lecture delves into the energy balance during pile driving, the dynamic soil resistance, and the estimation of static bearing capacity. Different empirical reduction factors and the concept of refusal during driving are also explained. The presentation concludes with practical applications of the formulas to estimate pile refusal criteria based on dynamic and static loads.
