钢管支架法在悬灌梁0号块施工中的应用

摘要

Combining with the construction practice of No. 133 cantilever pouring girder variable cross-section pre-stressed continuous box girder No. 0 block of Jingjiang flood diversion area large bridge,this paper introduced the design and build process adoption steel pipe support construc-tion of No. 0 block,and through the finite element software calculated the displacement,stress and strain index of steel pipe support system,to evaluate the safety of support system.%结合荆江分蓄洪区特大桥第133联悬臂灌注变截面预应力连续箱梁0号块的施工实践，介绍了采用钢管支架法施工0号块的设计与搭设过程，并通过有限元软件，计算得出钢管支架系统的位移、应力及应变指标，从而评价支架系统的安全性。
