Abstract: Taking the reinforcement of Maotan reservoir as study object, this paper introduces the existing safety hazards of the reservoir and the corresponding reinforcement scheme. The trial load method is used to conduct the structural safety calculation and analysis of the dam after reinforcement, and finite element analysis is employed for verification. The results of both methods indicate that the safety issues of the dam structure have been resolved. The paper also analyzes issues such as energy dissipation during discharge and seepage control on the dam surface. It is confirmed that the reinforcement measures for Maotan reservoir is effective, providing valuable reference for similar projects.

Key words: reinforcement, trial load method, finite element method, seepage prevention
