The construction methods of Yangtze river water intake project in Wuwei City include pipe jacking, trenching, borehole grouting pile and so on. The project has changed the water level and velocity conditions in nearby area, which has a certain adverse impact on the embankment seepage and stability of bank slope, but has no adverse impact on the overall and local stability of river regimes. In this regard, measures for embankment reinforcement, bank slope protection and foundation seepage prevention are put forward, and reasonable suggestions are put forward to further reduce the impact of flood.
