摘要
综合考虑洪峰与洪量双变量,提出了基于LHS-MC与Copula函数及三点式变倍比放大法的洪水漫坝率计算方法,计算了HYT水电站加固前后的洪水漫坝率,同时分析了洪量选择和风浪作用对结果造成的影响。结果表明,HYT水电站加固后有效提高了大坝的抗洪能力,且在漫坝率的计算中洪量选择和风浪作用均应计入考虑。可见所提方法具有较强的适用性,能较全面的考虑洪水的影响因素,在分析各类大坝的洪水漫坝率时合理有效。
Based on LHS-MC,Copula function and three-point variable ratio amplification method,a method for the calculation of dam overtopping rate is put forward in consideration of flood peak and flood volume.The dam overtopping rate of HYT hydropower station before and after reinforcement is calculated by this method,and the influence of flood volume selection and wind waves on the calculation results is analyzed.The results show that the flood resistance of HYT hydropower station can be improved effectively after reinforcement,and the flood volume selection and wind wave action should be taken into account in the calculation of dam overtopping rate.The proposed method has strong applicability since it can consider the influencing factors of flood comprehensively,and is reasonable and effective in analyzing the dam overtopping rate of various dams.
