摘要:
为系统指导径流峰值控制方案的制定，对海绵设施进行了归纳总结，采用调蓄池概化各种设施，采用模型模拟分析了不同调蓄雨量及不同调蓄方式对径流峰值控制的贡献。结果表明，当调蓄雨量由14 mm增至22 mm时，径流峰值削减率由40.0%增至71.3%，径流峰值削减作用十分明显，峰值出现时间相应延后了4.8~14.8 min。在源头全程调蓄、末端全程调蓄、末端脱过调蓄3种情况下，源头全程调蓄所需调蓄容积约为末端全程调蓄的50%，末端脱过调蓄所需调蓄容积约为末端全程调蓄的22%，据此给出了调蓄池布置的合理建议。此外，推求了一种管道流量过程线，以便不具备模型使用条件的区域计算调蓄容积。
Abstract:
The sponge facilities were summarized to systematically guide the formulation of peak runoff control scheme. Various facilities were generalized by storage tank, and the contribution of different rainwater storage capacity and modes to the peak runoff control was analyzed by simulation. When the storage capacity increased from 14 mm to 22 mm, the peak runoff reduction rate increased from 40.0% to 71.3%, the peak runoff reduction effect was very obvious, and the occurrence time of peak runoff was delayed by 4.8 min to 14.8 min. Among three storage modes, namely whole-course storage at the source, whole-course storage at the end and partial storage at the end, the storage volume required for the whole-course storage at the source was only approximately 50% of the whole-course storage at the end, and the storage volume required for the partial storage at the end was only approximately 22% of the whole-course storage at the end. Based on this, reasonable suggestions for the arrangement of the storage tank were proposed. In addition, a pipeline flow process curve was deduced to calculate the storage volume in areas without available models.
