预应力连续梁桥施工控制技术

预应力混凝土连续梁桥的施工方法很多,其中悬臂浇筑和悬臂拼装施工法应用最广.这种方法的采用,必然给桥梁结构带来较为复杂的内力和位移变化,为了保证桥梁施工质量和桥梁施工安全,桥梁施工控制必不可少.文章在分析总结国内外预应力混凝土连续梁桥发展和施工控制技术发展趋势的基础上,对大跨径预应力混凝土连续梁桥的施工控制技术进行了研究.

Construction Controlling Technology for Prestressed Continuous Beam Bridge

There are many construction methods of the PC continuous beam bridge.Among these methods,cantilever installation and cantilever casting have been used widely.This construction method results in the complex change of the intemal forces and displacements in the bridge.For ensuring the quality and safety of the construction,the construction control is indispensable.Through the analysis and summary of the development of continuous beam and the developmental tendency of the construction control techniques in our...
