- 摘要:
- 建设离线式削峰型调蓄空间是河渠提标的有效工程措施之一。由于目前缺少确定其启闭水位与计算调蓄容积的高效方法,以湖北省Z市城区某排涝系统为例,构建水力数值模型,采用“不利断面分析+推求水面线”的方式,快速确定分流开闸水位,形成分流闸实时控制(RTC)规则,从而优化调蓄空间设计。模型验证表明,基于该方法确定的调蓄设计方案可实现河渠精准削峰。相较传统的定积分矩形求解法,该方法在计算有效容积时,考虑了调蓄空间建成后分流断面上游顶托效应缓解以及管网-河渠汇流峰值流量增大的工况变化,更符合河渠削峰型调蓄空间的实际运行场景,计算结果更为精准可靠,可为城市建成区同类调蓄空间的设计提供参考。
- Abstract:
- Constructing offline peak-shaving storage spaces is one of the effective engineering measures for channel upgrading. However, efficient methods for determining the sluice trigger water levels and calculating the storage volume for such storage spaces are currently lacking. To address this gap, this research takes a drainage system in the urban area of Z city, Hubei Province as a case study. A hydraulic numerical model was developed, and a method combining critical section analysis with water surface profile derivation was employed to rapidly determine flood diversion sluice opening water levels. This facilitated the formulation of real-time control (RTC) rules for the diversion gate, thereby optimizing the design of the storage space. Model verification shows that the storage design scheme derived from this method achieves precise peak shaving. Compared to the conventional definite integral rectangular method for calculating effective storage volume, the proposed approach explicitly accounts for post-construction operational dynamics, namely the alleviation of upstream backwater effects at the diversion section and the increase in peak confluence flows from the stormwater network and channel. This approach better reflects the actual operating conditions of channel peak-shaving storage spaces, yielding more accurate and reliable computational results. It can provide a valuable reference for the design of similar storage spaces within urban built-up areas.
