摘要
水库泥沙淤积计算 ,作为水库工程设计的重要组成部分 ,直接影响到工程设计的质量。针对不同的适用性 ,分别介绍了一维恒定不平衡非均匀沙数学模型及拦沙效率经验面积减少法的计算原理、计算方法和计算中应注意的问题。同时 ,通过将其在云南省实际工程的计算成果与实测资料进行比较 ,证明这两种计算方法是合理可行的。
As a key component of reservoir design,the calculation of reservoir sedimentation will affect the quality of project design.According to adaptability in different regions in Yunnan,this paper presented respectively the calculation principle and calculation methods of the one_dimensional model of steady,unbalanced and non_uniform sand and empirical area_reduction method of trap efficiency and also problems which attention should be paid to during calculation.Comparison of calculated results and measured data of actual projects built in Yunnan showed that the calculation method is rational and practical.
