    摘要:

    在缺乏实测径流资料的地区开展河流模拟试验,径流、泥沙等参数的合理选取尤为重要。本文以某抽水蓄能电站下水库模型试验为例,对其坝址处的水文泥沙设计进行了研究。在进行径流系列设计时,采用水文比拟法对同流域有资料的水文站及设计水文站径流系列依次进行延长,得到坝址处1959~2012年54年的径流系列设计成果。在进行泥沙系列设计时,利用参证站泥沙实测资料与设计站少许资料,采用水文比拟法和经验公式法,分别对悬移质和推移质泥沙进行分析,推得参证站水沙关系式,再结合实际采样成果,推演出坝址处1959~2012年54年的泥沙系列设计成果。研究成果为动床物模试验与水沙数值模拟提供了必要的基础数据,采用的研究方法对缺乏实测径流资料地区的水文泥沙设计具有一定参考价值。

    Abstract:

    Reasonable selection of runoff and sediment parameters is very important to carry out river simulation test in areas where the measured runoff data is lacking. In this paper, a model test of the lower reservoir of a pumped storage power station is taken as an example to study the design of hydrological sediment at the dam site. In the design of runoff series, the runoff series of design hydrological station is extended by hydrological analogy, then, the fifty-four years results of runoff series design from 1959 to 2012 are obtained. In the design of the sediment series, using the reference station sediment measurement data and a little information of design station, utilizing hydrological analogy method and empirical formula method to analyze suspended sediment and bed load sediment respectively. As a result, water and sediment relations are obtained. Then combined with the actual sampling results deduce series of sediment design results from 1959 ~ 2012 years at the dam site. The research results provide the necessary basic data for the dynamic bed model test and the numerical simulation of water and sediment. The research method has certain reference value for the design of hydrological sediment in the area where the measured runoff data is lacking.
