| 摘 要： | 鄂东长江大桥为千米级混合梁斜拉桥,通过研究探明了鄂东长江大桥施工期结构行为特点,指出了超大跨度的混合梁斜拉桥具有非线性特征突出、边中跨的结构行为有一定的独立性等有别于全钢箱梁斜拉桥的特点。从施工期结构行为入手,就总体控制理念、边中跨控制重点、边中跨线形控制方法、施工期中跨钢箱梁应力调控、边跨应力控制、拉索张拉控制等关键技术问题进行了深入探讨。施工实践表明:实测结果与理论结果吻合较好,线形情况与应力情况对应,结构处于可控状态,证实了上述关键技术的有效性。

| Abstract: | The main bridge of Edong Changjiang River Bridge is a hybrid girder cable-stayed bridge with 1km main span.The structure behavior features of Edong Changjiang River Bridge's construction are introduced,including obvious non-linearity and independence between mid-span and side span in construction period,which are different from the features of steel box girder cabled bridge.According to structural behavior in construction period,overall control concepts,control key factors,line shape control method,stress c... |
