| Abstract: | Diamond-shaped cradle cantilever construction method is adopted for box girders of the prestressed concrete continuous rigid frame beams in the section of superstructures (116 200 220 200 116)m of the main bridge of the Dongying Yellow River Bridge. The paper introduces the support schemes respectively selected for construction of blocks No.0 of the main pier and secondary main pier and the cast- in- situ straight section. The trial loading method with cradles is explained and its trial loading results are analyzed. |
