摘要
现阶段,我国社会经济日新月异飞速发展,各行各业方兴未艾,我国交通事业也呈现一片蓬勃繁荣态势,在桥梁跨径增加的背景下,桥梁工程建设中,在广泛应用着预应力混凝土连续桥梁。现代大跨径桥梁施工种悬臂现浇施工法很常见,它有着十分复杂的施工过程,既要确保桥梁建设进度与质量,还必须确保结构在动力变化中能够满足桥梁完工后的线形和应力要求。所以,对此进行了详细论述和分析,其有着十分巨大的现实作用。
Nowadays,China's society and economy are developing rapidly with each passing day and all walks of life are in the ascendant.China's transportation industry is also showing a booming trend.Under the background of increasing bridge spans,prestressed concrete continuous bridges are widely used in bridge engineering construction.The cantilever cast-in-place construction method is very common in modern long-span bridge construction.It has a very complex construction process.It is necessary to ensure the progress and quality of the bridge construction,but also to ensure that the structure can meet the linear and stress requirements of the bridge after the completion of the dynamic changes.Therefore,it has been discussed and analyzed in detail,which has a very huge practical effect.
