摘要
某斜拉桥为混凝土梁+钢混组合梁的形式,上部结构边、中跨采用非对称平衡体系,通过采用对称悬拼施工与非对称悬拼施工方法比较,对于结构复杂的非对称平衡体系斜拉桥,需辅以临时支撑等措施,以减小塔顶偏位,对同类型桥梁施工具有指导意义。
A cable-stayed bridge is composed of concrete beam and steel-concrete composite beam. The superstructure side and middle span are constructed with asymmetrical balanced system. By comparing the construction methods of asymmetrical cantilever construction and asymmetrical cantilever construction, for cable-stayed bridges with complex asymmetrical balanced system, temporary support is needed to reduce the tower top deviation, which is of guiding significance for the construction of the same type of bridges.
