本桥位于广西壮族自治区境内湘桂铁路柳黎复线区间,全长398m,其中正桥桥跨结构为三跨连续双塔竖琴型,塔梁固结塔墩分离的预应力混凝土斜拉桥长192m,主跨96m,边跨48m,是目前国内第一座铁路斜拉桥。其跨径仅次于联邦德国第二美因河桥。在世界预应力混凝土铁路斜拉桥中是第四座,具有世界水平。斜拉桥具有跨越能力大、噪音小、抗风稳定性好、结构轻巧、外形美观和附加内力较小的优点。设计工作通过自编电算程序进行结构分析。通过桥梁模型、节点模型、缆索疲劳、缆索防护等试验以及高强度混凝土施工工艺试验等,积累了不少经验和科学数据,为在我国
The bridge is located in Guangxi Zhuang Autonomous Region of Hunan-Guangxi railway line Liuli double the total length of 398m, of which the bridge structure is a three-span continuous double-tower harp type, tower girder consolidation pier separated prestressed concrete cable-stayed bridge 192m long , The main span of 96m, while spanning 48m, is currently the first railway cable-stayed bridge in the country. Its span is second only to the Federal German second Main River Bridge. In the world of prestressed concrete cable-stayed bridge is the fourth, with world-class. Cable-stayed bridge has the advantages of large span, low noise, good wind stability, lightweight structure, beautiful appearance and small additional internal force. Design work through self-calculation program for structural analysis. Through the bridge model, the node model, the cable fatigue, the cable protection test and the high strength concrete construction technology test and so on, has accumulated a lot of experience and scientific data for our country
