跨越高速公路桥梁钢-混凝土组合梁施工方案研究

Research on Construction Scheme of Steel-concrete Composite Beam Crossing Expressway Bridge

以某钢-混凝土组合梁跨越既有高速公路施工为例,通过方案比选,确定了适合该工程的跨越方案。详细论证了该工程顶推施工方案的各个环节,优化了钢梁安装方案,减少了对既有高速公路的影响,保障了跨越施工的安全,可供类似跨越工程参考和借鉴。

Taking the construction of a steel-concrete composite beam crossing the existing expressway as an example,the crossing scheme suitable for the project is determined through the scheme comparison and selection.Each link of the incremental launching construction scheme of the project is demonstrated in detail,the steel beam installation scheme is optimized,the impact on the existing expressway is reduced,and the safety of crossing construction is guaranteed,so as to provide reference for similar crossing projects.
