摘要
预应力连续梁具有受力合理、施工方法灵活、适应性强、结构刚度大、整体性好、造价经济等优点,在当前得到了广泛应用。方家寨大桥采用先简支后连续的施工方法,通过逐次接长连续梁、逐次拆除临时支座来实现结构体系转换。
Prestressed continuous beam has advantages of reasonable load transter, flexible construction, high structure stiffness, good integrality and economical cost. It has been widely applied in bridge construction. Fangjiazhai Bridge is simply supported- continuous system. The structure system transformation has been implemented by successive extending beam and demolishing temporary support.
