所谓洪水漫顶,就是由于暴雨引起的洪水猛涨,漫溢到堤外或坝下,造成险情。洪水漫顶往往使堤坝溃决,损失极大,有时损失是毁灭性的。一、造成洪水漫顶的原因一是降雨过大,超过了工程规定标准。二是运用不当。由于担心汛后蓄不上水,使水库水位远远高于限制水位,当流域内降了设计标准雨量,也造成水库紧张,甚至出现 The so-called flood top, it is due to heavy rains caused by floods, overflow to the embankment or dam, resulting in dangerous conditions. Flood dams tend to make dike collapse, great loss, and sometimes the loss is devastating. First, the cause of flood top One is excessive rainfall, exceeding the engineering standards. Second, the use of improper. Due to the fear of flood storage after the flood, the reservoir water level is much higher than the limit water level, when the watershed design standards within the rainfall, but also caused the reservoir tension, or even appear
