The　cable-girder　anchorage　zone　of　cable-stayed　bridge　is　vital　to　the　safety　of　the　entire　structure.　Aiming　at　uniformly　conveying　the　vehicle　and　populaiton　load　as　well　as　the　load　of　the　main　girder　to　the　cables,　this　zone　shows　unique　characters　with　concentrated　and　massive　loads,　complex　structures,　comprehensive　load　paths　and　non-uniformly　stress　distributions.　This　paper　established　the　3D　finite　element　modal　for　the　Ronggui　Cable-Stayed　Bridge.　A　nonlinear　analysis　on　its　anchorage　zone　has　been　conducted　to　provide　reasonable　references　for　future　design　and　optimization.
