Abstract: The spillway of Qinghe reservoir has been in operation for 50 years. As time goes by, various risks encountered. Especially that the elevation of spillway diversion wall and the height of spillway chute wall could not meet the requirements of flood discharge, and the penetrating cracks on the pier exert adverse influence on safety of gate opening and flood discharge. Therefore, analysis on problems of the main structure of Qinghe reservoir spillway and review of its safety and stability are extremely urgent, as well as the further rehabilitation.

Key words: spillway, existing problems, safety, review
