In recent years, there has been an increase in natural disasters, such as large-scale debris flows, prompting considerations for reinforced measures for steel pipe Sabo dams. Consequently, there is a need for an analytical method to evaluate the reinforcement of steel pipe Sabo dams. The study analytically examines the damage factors of a steel pipe Sabo dam at a real scale to reproduce the damage cased by large-scale debris flow. Additionally, it investigates the reinforcement effects of increasing the number of joints and using joint covers under debris flow disaster conditions. Therefore, the proposed method can be an effective approach for evaluating and verifying retrofitting measures for existing steel pipe Sabo dams.
