Abstract: A theory for dynamic passive pressure for sand is developed. The theory is based on a simplified zero extension line field. Equations and charts for computing the dynamic coefficient of earth pressure for various values of wall roughness are presented. The theory is capable of predicting an engineering solution to dynamic passive pressures for the cases of translation, rotation about the top, rotation about the bottom into loose or dense sand. The results are in agreement but generally higher than those predicted by the rigorous methods of associated fields.
