摘要
为了了解江苏某多雨地区某尾矿库的防洪安全程度及排洪能力,采用地方公式与通用公式对该尾矿库进行了防洪安全与排洪能力计算,并进行了安全可靠性判断。结果表明,通用公式法计算的洪峰流量及洪水总量均大于地方公式法计算结果;该尾矿库采用排水塔—转流井—排水管系统排洪能力较优,能应对200 a一遇的洪水。
In order to understand the flood control safety degree and flood discharge capacity of a tail ings pond in a rainy area of Jiangsu Province,the local formula and general formula are used to calculate the flood control safety and flood discharge capacity of the tailings pond,and the safety reliability judgment is made.The results showed that the peak discharge and total flood amount calculated by the general formu la method are both greater than those calculated by the local formula method.The tailings pond adopts the drainage tower-diversion well-drainage pipe system for flood discharge,which has better flood discharge capacity.The drainage system of the tailings pond could cope with a flood once every 200 years.
