摘　　要：非洲某一项目水电站溢流坝段坝顶交通桥吊装条件差,现场没有足够起吊设备,鉴于非洲施工物资匮乏的实际情况,项目打破常规,采用现浇方法进行施工,工程按期安质完工。项目部对方案进行了充分论证,对底梁支撑体系进行了详细验算,并形成了1套完整的施工工艺流程及详细施工方法。For a project in Africa,the lifting condition of the traffic bridge on the dam crest of the overflow dam section is poor and there is not enough lifting equipment on site.Due to the shortage of construction materials in Africa,the project breaks the rule and is constructed by cast-in-situ method.The project is completed on time and with good quality.The project department has fully demonstrated the scheme,checked and calculated the bottom beam support system in detail,and formed a complete construction process and detailed construction method.
