| 摘 要： | 梧州桂江三桥设计为三孔自锚中承式钢管混凝土系杆拱桥，主拱跨径为175m，是我国首次采用集群液压千斤顶作动力装置进行竖转施工的钢管拱桥，施工中用钢绞线作柔性起重索，突破了以卷扬机钢丝绳滑车组的模式限制，大大提高了转体重量和提升高度，竖转高度和跨度居全国同类型桥梁之首。

| Abstract: | The third bridge over Guijiang River in Wuzhou city of Guangxi Zhuang Autonomous Region is a half through type steel pipe concrete tied arch bridge with three self anchored continuous spans. The main span is 175 m. Half span of main arch was prefabricated and transported with float boat, then erected with construction method of vertically turning body by group hydraulic jack as power device. The middle span of concrete arch was self balanced by side concrete arches. The paper introduces the construction summarized above. |
