It is shown possible in experiential and analytic studies that sleeve of sabo dam is damaged and destroyed by debris flow. A Technical Standard of Countermeasures against Debris Flow (Draft) disputes that the dam sleeve requires to be reinforced with iron bar and shaped steel if necessary. The standard, however, doesn't disputes a concrete design method considering impact response properties of reinforced concrete.<br>In Austria, most sabo dams with 5 to 20 meter height are made of reinforced concrete (hereinafter referred as RC sabo dam). The RC sabo dam is evaluated to be economical comparing with the gravity concrete dam, and to give flexibitiy to design of open type sabo dams.<br>As sabo dams to check debris flow and open type sabo dams such as slit dam have been increasing in recent years, it is necessary to study design method of RC sabo dam and reinforcing the dam sleeve. Subsequently, reinforcing with iron bar makes sabo dam ductile and strong in anti-earthquake.<br>As the RC sabo dam is more slender compering with concrete gravity sabo dam, it seems to tend unsafe against impact force by the debris flow. Although there are a few analytic and experimental studies on the impact response properties of RC sabo dam, no synthetic study of the design method is reported. Therefore, this paper aims to present a synthetic design method of RC sabo dam and reinforcement of dam sleeve considering ultimate-limit energy capacity.
