    摘要:

    坝系相对稳定与优化布局规划是当前小流域坝系建设研究的热点领域。在对坝系规划及坝系相对稳定研究和应用现状综述的基础上,依据系统动力学的原理,采用经验法、动态仿真法和非线性规划法建立了基于拦泥库容、滞洪库容、溢洪道流量优化设计的坝系布局优化模型和建坝时序优化模型,编制了坝系规划计算机自动优化流程图,并以陕北黄土丘陵区韭园沟小流域坝系优化为例,对模型进行了实例验证,取得了较好的应用效果,对黄土高原丘陵沟壑区小流域坝系建设优化规划有借鉴和指导意义。

    Abstract:

    Relative stability of dam system and its layout planning optimization are currently a hot area of the dam construction in small watershed.In this paper,the present situation of research and application about relative stability of dam system and its optimization design are reviewed at first.Optimization models of dam layout and construction timing are then established for the optimizations of intercepting sediment reservoir capacity,flood detention reservoir capacity,and design of spillway discharge by the principles of system dynamics,empirical method,dynamic simulation method,and non-linear programming method.Moreover,a computer flow chart of automatic optimization is presented.The optimization models of dam system are verified in Jiuyuangou watershed in the loess hilly area and desirable results are achieved.The study has a valuable reference for watershed dam construction in the similar areas of the loess hilly and gully area.
