中文摘要:

泥沙淤积是水库普遍存在的问题,为了解决汾河水库泥沙淤积的现状,本文基于泥沙随机沉降的原理,并结合汾河静乐水文站的历年实测资料,建立了汾河水库泥沙淤积的随机数学模型,通过2008年汾河水库淤积地形的模拟结果与2008年实测地形进行对比,验证了模型的准确性;应用模型对汾河水库库区泥沙淤积发展情况进行了模拟预测,通过模拟计算,汾河水库泥沙淤积呈三角洲形状,随淤积年限的增加,水库淤积体逐渐向坝前移动,水库运行20、50、60年后总库容由原来的6.94亿m3,分别减小到4.04亿m3、2.95亿m3、2.94亿m3。模拟结果为水库今后的运行和管理提供了科学的依据。

英文摘要:

The sedimentation in reservoir is a general existing problem.In order to solve the reservoir sediment problem,based on the principle of the s to chastic sediment settlement,combined with the measured data of the jingle hydrologic station in Fenhe River,has established the stochastic mathmatical model for the sedimentation in Fenhe reservoir.The feasibility of this numerical calculation method was verified by comparison with the real topography of Fenhe reservoir in 2008.The deposition development is simulat...
