摘要
以渠江特大桥为实际工程案例,介绍"堆载+反力"预压技术在挂篮预压中的工作原理、施工组织、观测手段及注意要点.结果表明此方法具有安全性高、操作性强、预压效果好等优点;同时能够实现减少材料投入、节约施工成本的目标,本次工程技术的成功应用也为大重量挂篮预压提供有益参考.
Abstract
Taking the Qujiang extra large bridge as an actual engineering case,this article introduces the working principle,construction organization,observation methods,and key points of the"stacking+reaction force"preloading technology in the hanging basket preloading.The results indicate that this method has the advantages of high safety,strong operability,and good preloading effect.At the same time,it can achieve the goal of reducing material input and saving construction costs.The successful application of this engineering technology also provides useful reference for the preloading of heavy-duty hanging baskets.
