Excel在大跨度桥梁桥面铺装拟合中的应用

The Application of Excel in Bridge Deck Pavement Fitting of Long- span Bridge

大跨度预应力混凝土连续梁桥、连续刚构桥多采用悬臂分阶段挂篮施工,施工过程中的桥面线形受诸多因素影响,现实状况必然与理想状况有差距,因此,对桥梁合拢后的桥面线形进行拟合显得尤为重要。Excel强大的数据分析功能为快速合理地解决桥面铺装的线形拟合问题提供了一条有效的途径。结合西格铁路大桥的施工监控实例,对桥面铺装拟合的方法进行探究,并通过实际数据整理出Excel在大跨度桥梁桥面铺装拟合中的合理应用。

Large span prestressed concrete continuous beam bridge,continuous rigid frame bridge mostly uses cantilever and phased hanging basket construction. Deck line during construction is influenced by many factors.Reality situation has a gap with the ideal consequentially. Therefore,the deck line fitting after the closure of the bridge is particularly important. Excel,with its powerful data analysis functions,offers an effective way to solve the linear fitting problem of bridge deck pavement reasonably. This paper combines the example on construction monitoring of Xi Ge railway bridge to research the method for bridge deck pavement fitting and achieve reasonable application of Excel in bridge deck pavement fitting of long- span bridge.
