Recently the debris flow disaster has been increased by global warming and localized torrential rain. This study presents the impact behavior of Sabo soil-cement dam which is proposed as a new type Sabo dam from both viewpoints of cheep construction cost and the effective utilization of field sediment. First, in order to compare with the characteristics of Sabo soil-cement dam, the impact behaviors of the concrete Sabo dam sleeve and the steel pipe Sabo dam member are investigated by impact response analysis using the computer code LS-DYNA. Then, the impact behavior of Sabo soil-cement dam sleeve is examined by changing the parameter of soil-cement and steel plate thickness. Finally, an impact design concept of Sabo soil-cement dam is proposed from the impact behavior results.
