丰满大坝始建于1937年,1942年采用临时断面蓄水,1943年发电;1948年和1949年进行恢复工作;1951～1953年按《366号设计》进行了扩建和改建;1953年全部建成.由于施工质量差,混凝土强度低,稳定性及整体性差,又长期风化、冻胀、坝体漏水和溶蚀,虽经不断的维护.破损老化严重.1986年溢流面遭受到破坏,大坝还存在防洪能力低、抗震能力不够等问题.从此对大坝进行加固,1997年基本结束. Fengman dam was built in 1937, 1942 temporary section water storage, power generation in 1943; 1948 and 1949 for restoration work; 1951 ~ 1953 according to “366 Design” was expanded and rebuilt; all completed in 1953 Due to poor construction quality, low concrete strength, poor stability and integrity, and long-term weathering and frost heaving, the water leakage and corrosion of the dam body are continuously maintained, the damage and aging are serious, and the overflow surface was damaged in 1986. The dam There are also some problems such as low flood prevention capacity and insufficient seismic capacity, etc. Since then, the dam reinforcement has basically ended in 1997.
