Abstract: As a key water conservancy project in Shajingzi irrigation area of the first division of Xinjiang Production and Construction Corps, Xinjingzi reservoir faces multiple challenges such as insufficient seepage safety, decreased regulation and storage capacity and structural damage. The reinforcement proj ⁃ ect is designed based on existing problems, including raising and optimizing the dam crest structure, adopting multiple measures to reinforce the main and auxiliary dams to enhance seepage prevention and stability, using Autobank 6.0 software to calculate the seepage stability of dam and the anti-sliding sta ⁃ bility of dam slope, rebuilding and repairing the water discharge gate to enhance water discharge effi ⁃ ciency, reconstructing channels and dredging to enhance water diversion efficiency and water quality, and introducing the information automation and monitoring system to achieve real-time monitoring and precise management of the reservoir operation data. The results indicate that all safety indicators of the reinforced reservoir meet the design requirements, which significantly improves the operation safety and storage capacity of reservoir. This study emphasizes the importance of continuous monitoring and mainte ⁃ nance, providing reference for similar projects.
