一、洪水估算方法的发展在现代,大坝的高度已突破300米,并向更高的方向发展,大坝是一种巨大的建筑物.如果设计洪水偏低或设计施工不当,就会造成险库,大坝一旦溃决,垮坝洪水冲击波将给下游人民生命财产带来毁灭性灾害.根据现有资料,约有30%垮坝是由洪水漫顶所致,可见洪水估算在大坝设计中是一个极为重要的环节.所谓设计洪水计算就是推算过去未发生或已发生而未记录,但今后却有 First, the development of flood estimation method In modern times, the height of the dam has exceeded 300 meters, and to a higher direction, the dam is a huge building.If the design flood is low or improper design and construction, it will cause According to the available information, about 30% of the failures are due to flood overrun. It can be seen that the estimation of flood in dam design Is a very important part of the so-called design flood calculation is calculated in the past did not occur or have not been recorded, but in the future
