管道穿越河道防汛安全影响分析

Analysis on Influence of Pipeline Crossing River on Flood Control and Safety

上海市中心城区道路积水改善工程中,排水管道穿越河道常采用非开挖顶管施工方法。以虹口区某道路积水改善工程为例,提出管道穿越段防汛墙改建方案,并采用有限元计算软件分析了顶管穿越河道施工对防汛安全的影响,为开展相关设计及防汛安全影响分析工作提供一定的参考价值。

In the road waterlogging improvement project of the central urban area in Shanghai, the trenchless pipe-jacking construction method is commonly used in the drainage pipeline crossing river. Taking a road waterlogging improvement project of Hongkou District as an example, this paper puts forward the flood control wall reconstruction scheme of pipeline crossing section, and analyzes the influence of pipe-jacking crossing river construction on the flood control and safety by using the finite element calculation software, which provides a certain referring value for carrying out the relative design and analysis of flood control and safety influence.
