Residual　soil　filled　embankment　failures　have　been　the　major　part　of　landslide.　The　landslide　event　occurred　at　the　filled　embankment　adjacent　to　the　bridge　abutment　of　Tudiyang　Bridge　at　Nanping　Section　of　Beijing-Fuzhou　Expressway　has　been　analyzed;　and　some　factors　affected　on　the　residual　soil　filled　embankment　failure　have　been　analyzed.　The　rainfall　infiltration,　as　the　most　important　factor,　affected　on　this　landslide　event.　Based　on　the　parametric　evaluation　of　the　residual　soil　filled　embankment　failure,　such　mechanism　analysis　of　filled　embankment　stability　has　been　given.　And　the　landslide　were　also　caused　by　other　triggering　factors　including　the　compacting　factor　of　residual　filled　soil,　the　residual　soil　characteristics　and　the　slaking　deformation.　The　results　offer　engineering　treatments　of　designing　the　high　residual　soil　filled　embankment　and　controlling　the　quality　of　construction.
