摘要
大跨度连续梁桥梁施工中,临时固结作为保证大跨度连续梁施工安全的关键措施,其安全性、稳定性及经济适用性是施工过程中控制的重点及难点。基于鄱余特大桥工程项目,通过对两种常见临时固结方案的经济性、安全性进行分析对比,确定了该工程大跨度(83+152+83)m波形钢腹板连续梁施工中采用的临时固结方案,并详细介绍了临时固结方案的设计及计算内容。
In the construction of long-span continuous beam bridge,temporary consolidation is the key measure to ensure the construction safety of long-span continuous beam,and its safety,stability and economic applicability are the key and difficult points in the construction process.Based on the Poyu super large bridge project,this paper analyzes and compares the economy and safety of two common temporary consolidation schemes,determines the temporary consolidation scheme adopted in the construction of large-span(83+152+83)m continuous beam with corrugated steel webs,and introduces in detail the design and calculation contents of the temporary consolidation scheme.
