“…1(b)). We note that the Winkler model is the simplest one can use to represent the soil, and is adopted herein precisely because of its simplicity and common use in practice [32,33]; however, the described methodology can readily accommodate more sophisticated soil models (e.g., [34,35]) without substantial changes to the approach. The wave propagation physics associated with the mathematical model shown in Figure 1(b) can be described by the following partial differential equation (PDE):…”

“…where 𝐺 𝑠 and 𝜈 𝑠 are the underlying soil's shear modulus and Poisson ratio, respectively, and 𝑟 𝑡 is the pile's radius at the toe. Using customary values and (35), we set 𝑘 𝑏 to 300.8 MN/m, and seek again to characterize both a homogeneous soil profile (Example 2a), and a three-layer profile (Example 2b), using the same target data as in Example 1. Figures 8(a) and 9(a) depict the recorded pile head IR data for the two soil profile cases, while Figures 8(b) and 9(b) show the initial guess, the target, and the reconstructed soil profiles.…”

“…L'art de cette technologie au principe élémentaire, pour ne pas dire barbare, réside dans la modulation de l'impact, tant en amplitude qu'en durée, afin de vaincre la résistance du sol mais sans toutefois dépasser la résistance structurale du pieu à installer. La méthode alternative du vibro-fonçage décrite par Holeyman et Whenham (2015, 2017 ne fait pas l'objet de cet article.…”
