An Excel spreadsheet has been presented to predict the earthquake-induced sliding displacement of slopes in Iran using 3319 Iranian earthquake records and more than 1,510,000 Coupled stick-slip-rotation (CSSR) analyses.

Downward movement of sliding soil mass in earthquake-induced earth slopes may gradually improve the system's stability. Hence, a significant change in critical (or yield) acceleration of the slope is anticipated. The existing simplified coupled procedures, however, assume a constant critical acceleration in stick-slip sliding analysis. Fully coupled sliding block analyses with continuously increased critical acceleration were conducted to estimate the earthquake-induced permanent displacement of earth slopes. The sliding mass was assumed as a flexible chain moving along the planes with gradually gentler inclinations.
