[Objective] To measure the effect of EN-1 soil stabilizer on soil anti-collapse ability in order to provide the theoretical basis for immobilizing the bank slope. [Methods] By utilizing indoor disintegration experiments in static water, disintegration amount and disintegration rate were studied under certain conditions which included the proportion of EN-1 soil stabilizer at 0(pure soil), 0.05%, 0.10%, 0.15%, 0.20%, and 0.30%, the compactness at 0.85, 0.90, and 0.95, and the maintaining period during 3 d, 7 d, 15 d, respectively. [Results] Solidified soil disintegration amount decreased significantly compared with pure soil along with the increasing amount of EN-1 stabilizer and maintaining period which were designed in experimental scheme. [Conclusion] With the view of the effective utilization rate and economy, soil-reinforcement is significant when the appropriate proportion of stabilizer was 0.20%, the maintaining period was at least 7 days, and the compactness was no less than 0.90.
