对国内外已建、在建和拟建200 m以上超级高坝进行统计表明，国外超级高坝建设起步较早，发展持续不断，我国起步较晚，但发展较快；超级高坝主要集中在混凝土拱坝、混凝土重力坝、土心墙堆石坝和混凝土面板堆石坝等4种坝型，已建工程都能安全可靠运行。通过分析我国水电工程发展趋势以及工程特点，我国超级高坝的发展面临安全要求高、相关技术标准缺乏、关键技术需联合攻关、风险防控和全寿命周期的有效管理等方面的挑战。
對國內外已建、在建和擬建200 m以上超級高壩進行統計錶明，國外超級高壩建設起步較早，髮展持續不斷，我國起步較晚，但髮展較快；超級高壩主要集中在混凝土拱壩、混凝土重力壩、土心牆堆石壩和混凝土麵闆堆石壩等4種壩型，已建工程都能安全可靠運行。通過分析我國水電工程髮展趨勢以及工程特點，我國超級高壩的髮展麵臨安全要求高、相關技術標準缺乏、關鍵技術需聯閤攻關、風險防控和全壽命週期的有效管理等方麵的挑戰。

The statistics on high dams with a height more than 200 m in abroad and home under operation, construction or planning shows that the super high dam construct earlier and continues to develop in foreign countries, and starts later in but rapid in China. The super high dams mainly belong to concrete arch dam, concrete gravity dam, clay core wall rockfill dam or concrete face rockfill dam, and all super high dams which have been put into operation can safely and reliably operate. The development and characteristics of hydropower engineering in China are analyzed and the result shows the development of super high dams in China will face the challenges of high safety requirement, lack of relevant technical standards, joint research requirements on key technologies, risk prevention and control and effective management in whole operation life.
