Abstract:Small-sized reservoirs are critical to the safety of flood control of reservoirs, and also undertake multiple functions such as irrigation, water supply and ecological services. The implementation of danger removal and reinforcement is essential to ensuring the safe operation and comprehensive benefits of small-sized reservoirs. By sorting out and analyzing the stages of dam safety appraisal, preliminary design of danger removal and reinforcement, and engineering construction of small endangered reservoirs in Shandong Province, this paper summarizes the typical problems existing in each stage of danger removal and reinforcement work, and puts forward relevant opinions and suggestions, so as to provide reference and guidance for the reinforcement of small endangered reservoirs.
