钢箱梁顶推施工过程导梁的计算分析与监测

Calculation Analysis and Monitoring of Guide Beams during Steel Box Girder Jacking Construction Process

钢箱梁顶推施工是桥梁建设中常见的施工方法。通过对钢箱梁顶推施工全过程进行计算,分析钢导梁在整个施工过程中的应力及位移变化,通过实际监测结果与理论计算分析值进行对比,结合应力自动化监测结果,实时了解结构的受力状态,为顶推施工提供技术支持。

Steel box girder jacking construction is a common construction method in bridge construction.By calculating the entire process of steel box girder jacking construction,analyzing the stress and displacement changes of the steel guide beam during the entire construction process,comparing the actual monitoring results with the theoretical calculation analysis values,and combining with the stress automation monitoring results,the stress state of the structure can be understood in real time,providing technical support for top pushing construction.
