摘要
以大西客专灞河特大桥跨北环线铁路的连续梁采用反力架预压施工为例,在提出预压方案的基础上,介绍了预压准备工作,阐述了挂篮预压基本测试流程,经加载很好地验证了各构件的安全性,从而取得很好的经济、社会效益。
Taking the reaction frame construction applied in the continuous beam of Da-Xi passenger special Babe bridge crossing north ring rail-way as an example, based on preloading scheme, the paper introduce the preloading preparation work, and describes the basic testing procedure of hanging basket preload. The loading better testifies the structural security, so as to achieve good economic and social benefits.
