【摘要】：水库联合调度作为城市防洪的非工程措施发挥着越来越重要的作用,但是随着水库数目的增多,由于数学模型概化及优化技术的局限性(如动态规划中的"维数灾"问题),水库优化调度及其规则的制定变得越来越困难。为此,针对城市防洪规划中水库群的防洪调度规则制定,以城市防洪控制断面的过流能力为约束条件,提出了正逆两向的水库联合调度分析方法,以都匀市已有和规划水库群的联合调度为例,验证了提出方法的合理性与可操作性。结果表明:逆向分析方法相比正向分析方法相比更能减小水库调度方案制定的不确定性,结果也可为类似的城市防洪规划提供参考和借鉴。
[Abstract]:As a non-engineering measure of urban flood control, joint operation of reservoirs plays an increasingly important role, but with the increase of the number of reservoirs, Due to the limitation of mathematical model generalization and optimization techniques (such as "dimension disaster" problem in dynamic programming, it is becoming more and more difficult to make reservoir optimal operation and its rules. Aiming at the regulation of flood control operation of reservoir group in urban flood control planning, taking the overflow capacity of urban flood control section as the constraint condition, a forward and inverse analysis method of reservoir joint operation is put forward. Taking the joint operation of existing and planned reservoirs in Duyun City as an example, the rationality and maneuverability of the proposed method are verified. The results show that the reverse analysis method can reduce the uncertainty of reservoir operation scheme more than the forward analysis method. The results can also provide reference for similar urban flood control planning.
