| Abstract: | Taking a prestressed concrete continuous bridge as an example, using finite element software to analysis the girder nodes' elevation subsequent change when six factors change which are related to continuous bridge's geometric control. The corresponding control proposals are proposed for each influencing factors in order to provide some reference for the similar bridges' geometric control work. |
