摘　　要： 提出了编制江河取水泵站二参数工况谱的方法:根据取水泵站的工况特点选取水源水位为基准参数,利用概率理论确定水源水位和日用水量的联合概率分布,定量地描述取水泵站的工况范围及变化规律。建立了基于工况谱取水泵站优化设计模型,并利用完全枚举和既约梯度法相结合的方法对模型进行了求解,通过实例证明了该方法的有效性。 A formulation method of two-parameter operating condition spectrum for intake water pump station is put forward. After water-level of the source river is selected as norm according to the required operating condition of the intake water pumping station, the joint probability distributions of water level and daily water demand are statistically determined to quantitatively define the variation and the margin of the working conditions for the pumping station. The models based on operating conditions spectrum are developed for optimal design of water pump station. The enumeration and Wolfe reduced gradient method are used to solve the model. The sample has testified the validity of the method.
