顶推通道上一座大桥桥梁方案研究

Research on Scheme of a Bridge on Incremental Launching Channel

以一座黄河特大桥顶推通道上的大桥为例,本着"永临结合"的思路,分析研究了3种桥梁方案,并通过有限元分析软件Midas Civil对主要构件进行了验算。对确定的推荐方案进行了再次优化,确保各阶段桥梁结构安全,施工方便,降低工程造价。

Taking a bridge on the incremental launching channel of Yellow River Bridge as an example,three bridge schemes were analyzed and studied based on the concept of permanent and temporary combined facilities, and the primary members were checked and calculated by the finite element analysis software, Midas Civil. The recommended scheme was optimized again to ensure the safety of the bridge structure on each stage.This scheme is convenient for construction and can reduce the project cost.
