摘　　要：南铁门山水库水库大坝为三类坝,目前水库工程各建筑物出现不同程度的安全隐患,亟需进行工程加固达标建设。针对大坝安全存在的主要问题,大坝坝顶道路不满足规范要求,坝坡无排水措施,平整度较差。溢洪道无法发挥溢洪道功能。输水涵存在渗漏现象。水库无监测、观测设施。对大坝上游混凝土护坡修复、改建溢洪道、重建放水涵、新建贴坡反滤、新建大坝观测设施、新建水库管理房及防汛路,实现了大坝坝体防渗达标稳定运行。South Tiemenshan Reservoir Dam is a Class III dam.At present,there are varying degrees of safety hazards in various buildings of the reservoir project,and it is urgent to carry out engineering reinforcement and construction to meet the standards.The main problems with dam safety include non-compliance of the road on the dam crest with regulatory requirements,lack of drainage measures on the dam slope,and poor flatness.The spillway cannot function as a spillway,there is leakage in the water conveyance culvert,and there are no monitoring and observation facilities in the reservoir.By taking measures such as repairing the upstream concrete slope protection of the dam,rebuilding the spillway,rebuilding the drainage culvert,constructing slope filtration,constructing dam observation facilities,constructing reservoir management houses,and flood control roads,the dam has achieved stable operation with anti-seepage standards.
