摘要
结合通天河大桥主桥连续梁挂篮预压的实例,在阐述千斤顶反力架预压挂篮施工技术的基础上,介绍了反力架临时结构安全验算及预压成果,通过挂篮预压验证了构件的安全性,并指出采用该技术便于施作,具有较好的经济效益。
Combining with the examples of continuous beam hanging basket preloading of Tongtian river bridge, based on elaboration of preload- ing hanging basket construction technology of jack reaction frame, introduced the safety check and preloading results of reaction frame temporary structure, through the hanging basket preloading verified the security of component, and pointed out that using this technology easy to implement, had good economic benefits.
