摘要
以合肥市安徽农业大学内涝点改造设计为例,在分析主要积涝成因基础上,提出将排水系统按高、低排区划分,通过水力模型的建立,在遭遇外河常洪水位等条件下分别进行评估分析,根据模拟结果优化工程设计,以最小的改造代价将片区排水标准提高至重现期P=5年一遇。
In this paper, we took the waterlogging transformation of Anhui Agricultural University in Hefei as an example, to demonstrate how the hydraulic model was used. In this application, the main flooding cause was identified, and the drainage system of the university was divided into high and low -level drainage base areas, then we built the hydraulic model to evaluate the drainage capacity un- der normal level and flood level of the outer river respectively. Based on the simulation result, the engineering design for the waterlogging remediation could be optimized, and the flood recurrence in- terval could be extended to 5 years with the minimum cost.
