本发明涉及水库调度技术领域，具体是一种考虑跨流域调水影响下的水库分期汛限水位优化设计方法。The invention relates to the technical field of reservoir dispatching, in particular to a method for optimizing the design of the flood-limited water level of a reservoir by stages under the influence of cross-basin water diversion.
背景技术Background technique
由于受季风气候影响，我国降水分布不均，从而导致我国水资源呈现时空分布不均的特征。水库是协调流域水资源进行合理配置的主要工程措施。目前，水文学者以水库(群)为研究对象，在水资源调配理论与方法层面已取得了大量的科研成果，并逐步形成了较为成熟的技术方法体系；但水库对水资源的调蓄作用多局限于流域干或支流范围内。对此，跨流域调水是通过大规模的人工方法从余水的流域向缺水流域大量调水，以便促进缺水区域的经济发展和缓解流域用水矛盾，可与水库进行水工程联合运用，从而实现水资源在流域“宏观”与“微观”双重尺度上的安全高效协调分配。跨流域调水工程的具体实施通常需要先分析流域洪水资源分布特征并明确水库水源区可调水量，然后从水库坝前修建引水工程将余水调至受水区。因此，新时期开展水库(群)洪水资源化利用研究需要考虑跨流域调水会对水库入库洪水过程产生影响这一前提条件，这也是实现水工程(水库与跨流域调水工程)间联合调度、流域水资源优化配置的关键。其中，汛限水位是水库优化调度的关键特征水位参数，以此为切入点开展水库调度与跨流域调水工程联合运用是值得探究的。Due to the influence of the monsoon climate, the distribution of precipitation in my country is uneven, which leads to the uneven distribution of water resources in time and space in my country. Reservoir is the main engineering measure to coordinate the rational allocation of water resources in the basin. At present, hydrologists take reservoirs (groups) as their research objects, and have achieved a lot of scientific research results in the theory and method of water resources allocation, and gradually formed a relatively mature technical method system; but the role of reservoirs in regulating and storing water resources Most are confined to the main or tributary of the watershed. In this regard, inter-basin water transfer is to transfer a large amount of water from the remaining water basin to the water-deficient basin through large-scale artificial methods, so as to promote the economic development of the water-deficient area and alleviate the contradiction of water use in the basin. It can be used in conjunction with the reservoir for water engineering. So as to realize the safe and efficient coordinated distribution of water resources on the "macro" and "micro" scales of the basin. The specific implementation of the inter-basin water transfer project usually requires analyzing the distribution characteristics of flood resources in the basin and clarifying the adjustable water volume in the reservoir water source area, and then constructing a water diversion project in front of the reservoir dam to transfer the remaining water to the water receiving area. Therefore, in the new era, the research on the utilization of flood resources in reservoirs (groups) needs to consider the precondition that cross-basin water transfer will affect the flood process of the reservoir inflow. The key to scheduling and optimal allocation of water resources in the basin. Among them, the limited water level during the flood season is the key characteristic water level parameter for the optimal operation of the reservoir. Taking this as the starting point to carry out the joint application of the reservoir operation and the inter-basin water transfer project is worth exploring.
在现有的技术中存在如下问题：(1)现有水库分期汛限水位优化设计研究未考虑跨流域调水工程对入库洪水过程的影响；(2)目前针对水库分期汛限水位优化设计研究主要以传统洪水风险率作为防洪标准进行评价，在径流变化环境下适用性存在可探讨的空间。There are the following problems in the existing technology: (1) The existing research on the optimal design of the flood-limited water level of the existing reservoir does not consider the impact of the cross-basin water transfer project on the flood process; The research mainly uses the traditional flood risk rate as the flood control standard for evaluation, and there is room for discussion in the applicability under the environment of runoff change.
