摘要:
修建跨河桥梁时,由于桥墩占据了部分过水断面面积,桥孔压缩水流,使桥位上游水面壅高,形成桥前壅水,影响防洪排涝安全。以纬七路跨秦淮河大桥为研究对象,总结了近年来常用壅水计算公式和水利行业常用规范公式,利用MIKE二维模型对桥址处上、下游约2km河道进行建模计算,最后采用经验公式计算建桥后河道最大壅水高度,并与模型结果进行分析比较,总结各计算方法优缺点及适用性,为其他类似工程提供参考。
Abstract:
When constructing a bridge crossing river, due to the bridge piers occupying a portion of the cross-sectional area of the water flow, the bridge opening compresses the water flow, causing the upstream water surface of the bridge site to rise, forming a backwater in front of the bridge, which affects the safety of flood control and drainage. This article takes the Weiqi Road Bridge crossing Qinhuai River as the research object, summarizes the commonly used calculation formulas for backwater in recent years and the commonly used standard formulas in the water conservancy industry. The MIKE two-dimensional model is used to model and calculate the upstream and downstream river channel of about 2 kilometers at the bridge site. Finally, empirical formulas are used to calculate the maximum backwater height of the river channel after the bridge is built, and compared with the model results. The advantages, disadvantages, and applicability of each calculation method are summarized, providing reference for other similar projects.
