摘要
以湘江特大桥小岔河桥的施工合龙方案为依据,从成桥部分受力状态、施工控制预拱度、施工工艺可行性等方面,粗略分析了分步施工与同步施工的不同,为同类桥梁的施工提供了参考。
Based on the construction closure scheme of Xiaochahe Bridge of Xianggjiang Grand Bridge, this paper analyzes the differences between synchronous construction and step-by-step construction from aspects of completed bridge part＇s stress state, construction controlled pre-camher, and construction technique＇s feasibility, etc., providing references for the construction of similar bridges.
