摘要
来宾磨东红水河大桥主桥跨度为180m的上承式钢筋混凝土桥梁,采用缆索吊装斜拉扣挂悬臂拼装施工。通过工程实例,对大桥进行了施工控制计算,并对施工过程中拱肋结构的平面应力分布情况进行了分析,并对其效果进行了评价。
The main bridge of Laibin Modong Bridge is a deck type concrete arch bridge with span of 180m,which is constructed by precasted segmental cantilever method.The spatial finite element programe-Super SAP is used to analyse the construction control of this bridge .
