摘要:
在桥墩概化、模型验证和参数分析率定基础上,建立秦淮新河涉水桥群二维整体数学模型,对秦淮新河不同水文条件下桥群叠加阻水对行洪能力的影响进行计算分析。结果表明:秦淮新河河道水流受桥群阻水叠加影响,尤其在中上游,桥墩布置密集,河道壅水明显,在一定程度上消弱了秦淮新河的行洪能力,对行洪安全造成一定影响。
Abstract:
Based on the generalization of bridge piers, model verification and parameter analysis, the two-dimensional mathematical model of the new Qinhuai River wading bridge group was established, and the influence of water blocking superimposed on flood discharge capacity under different hydrological conditions was calculated. The results showed that the water flow was affected by the superimposed water blocking of the bridge group, especially in the middle and upper reaches. The piers were densely arranged and the rivers were drowning, to some extent, the flood control capacity of the new Qinhuai River was weakened, which had a certain impact on flood safety.
