摘要
明月峡长江大桥为双层四线钢桁架斜拉桥矮塔斜拉桥,采用OVM250A钢绞线斜拉索。重点介绍了OVM250A钢绞线拉索结构及挂索施工工艺,进一步了解了明月峡长江斜拉桥的悬臂挂篮施工,实践证明OVM250A钢绞线拉索技术安全可靠。
Mingyuexia Yangtze river bridge is a double-layer four-strand steel truss extradosed cable-stayed bridge,with OVM250A steel strand cable.The OVM250A steel strand cable structure and construction technology of hanging cable are introduced emphatically,so as to further understand the cantilever hanging basket construction of Mingyuexia Yangtze river cable-stayed bridge.The practice shows that the technology of OVM250A steel strand cable is safe and reliable.
