New Method to Predict Crater Depth Obtained in Dynamic Compaction

This article presents a method to estimate dynamic compaction crater depth using empirical equations. As main reference, three physical model studies that used sand and clay soils were considered (Jafarzadeh in Proceedings of the international conference on performance-based design earthquake geotechnical engineering, pp 1–8, 2006; Arslan et al. ICE Ground Improv 11(2):61–66, 2007; Yuan Geotech Geol Eng 36:1873–1883, 2017). These variables such as weight (W), height (H), soil density (γnat), number strikes (N) angle at bottom hammer (θ). It was possible plot relation E versus ρ (Energy vs. Depth produced) adequately well craters depths. The linear correlation between α Factor) β (Stiffness factors observed (R2 0.93 1), considering following parameters: (H) (γnat). Also, η (Wcosθ /AH γ) (αβ)0.5 presented R2 0.91 0.8, use hammers with different weights affect (αβ)0.5. After calibrating, it is predict development based blows proposed model. linear, it’s practical them prediction definition effective influence other formulas expressed literature.
