摘要
合拢段施工是连续梁施工和体系转换的重要环节,如何在温度变化时,保证合拢段混凝土的质量,是合拢成功与否的关键。根据合拢时的受力分析,结合张家港大桥合拢段施工的实践,提出采用强大的体外刚性支撑临时锁定的方法,可供类似桥梁施工时参考。
Closure section erection is the key phase for the construction and structural system trans formation of continuous beam. The quality guarantee of the concrete is crucial to the success of the joining under temperature changes. Combined with the practice of construction of the Zhangjiagang bridge, a cal culation method and rigid bracing in closure presented can be a reference for similar bridges construction.
