摘　　要：临时墩的设置在钢箱梁顶推施工过程中起着十分重要的作用,因此有必要对临时墩进行计算复核,分析临时墩在顶推过程中是否满足设计要求,验证临时墩设置的合理性。文章以汕头市濠江区某下承式钢箱提篮拱桥为例,介绍项目内容及顶推施工工艺,并总结钢箱梁提篮拱桥顶推施工安全的影响因素及控制措施,并通过计算复核验证了临时墩设置的合理性,研究成果可为类似钢箱提篮拱桥施工提供有效参考。The setting of temporary piers plays a very important role in the jacking construction of the steel box girder.Therefore,it is necessary to calculate and review the temporary piers,analyze whether the temporary piers meet the design requirements in the jacking process,and verify the rationality of the temporary pier setting.Taking a bottom-loaded steel box basket arch bridge in Haojiang District of Shantou City as an example,this paper introduces the project content and jacking construction technology,summarizes the influencing factors and control measures of jacking construction safety of steel box girder basket arch bridge,and verifies the rationality of temporary pier setting through calculation and review.The research results can provide effective references for the construction of similar steel box basket arch bridges.
