猛洞河大桥缆索吊装方案设计和施工

海螺猛洞河大桥是典型的大跨度钢管混凝土拱桥,构建于深切峡谷之上,由于地理条件的限制,海螺猛洞河大桥的拱圈施工采用缆索吊装法施工.论述了该桥在采用缆索吊装法中,缆索吊装、斜拉扣挂方案的具体布设和主要施工工艺,对主缆和扣索的受力做了较为详细的检算.研究结果表明,缆索吊装法方法适合于猛洞河大桥的施工,缆索吊装、斜拉扣挂方案是否安全可靠关系到整个成桥的质量,因此,本文研究结论对类似桥梁建设具有参考意义.

Erection with Cableway Scheme Design and Construction of Mengdong River Bridge

Mengdong river bridge is typical of large-span steel pipe concrete arch bridge which built on deep canyon.because of geographical constraints,arch ring construction of the bridge erection wih cableway.this article discusses the main construction plan and technics of the cableway erection,strayed knotting methed,and the checking calculation of the main cable and buckling cable.the researches show that erection with cableway and strayed knotting methed is applied to mengdong river bridge.these projects bearing on the quality of the entire bridge.Therefore,the conclusion ofthe study on bridge-like construction of reference importance of this article.
