摘　　要：高刚性特征的连续刚构桥得到了越来越多的借鉴使用,其中100~300m跨度的大跨度连续刚构桥已成为公路基础建设中非常普遍的桥梁结构。而大跨度连续刚构桥在使用过程中,出现了刚度衰减、挠度增加等各种问题。因此,文章研究了高速铁路大跨度连续梁挠度控制技术,以供参考。Continuous rigid frame bridges with high rigidity characteristics have been increasingly used for reference,among which large-span continuous rigid frame bridges with a span of 100~300 meters have become a very common bridge structure in highway infrastructure construction.However,during the use of large-span continuous rigid frame bridges,various problems such as stiffness attenuation and increased deflection have occurred.Therefore,the article studied the deflection control technology of large-span continuous beams in high-speed railways for reference.
