Abstract: Construction of bridge projects and facilities across the river,through the river,through the embankment,riverside is easy to cause the near shore water level to rise and increase in velocity,and has adverse impact on the banks of the embankment and local bank slope.In order to analyze the influence of the reconstruction project of Niushou super large bridge of Hanjiang River on safety of Wolong embankment,based on the geohydrogeological data,a seepage analysis model of finite element calculation was established.The seepage anti-sliding stability of the embankment before and after the construction of the reconstruction project were analyzed.
