| Abstract: | The bridge of the No.4 Line of the Guangzhou Track-way Project is a 3-span continuous girder bridge with a 65-m span as its main span,which is cantilevering assembled section by section with a cantilever crane mainly consisting of the Bailey beam.The structure and the examination of the cantilever crane,and the cantilevering assembling techniques for the non-uniform main beams are introduced in the paper.Our construction practice shows that cantilevering assembling continuous girders section by section has the advantages of being short in construction duration,good in quality,lower in cost,good in adaptability,capable of ensuring safe construction,etc. |
