摘　　要：兰州小西湖黄河大桥主桥为一联(81.2m+136m+81.2m)预应力混凝土双塔单索面部分斜拉桥。为了检测桥梁结构的静力和动力性能,鉴定桥梁的承载能力,对该桥进行了静动载试验,并将试验结果与理论分析结果进行了比较,结果表明,该桥的设计计算可靠,施工质量优良。The main bridge of Xiaoxihu Yellow River Bridge is a prestressed concr ete partial cable-stayed bridge whose span is 81.2m+136m+81.2m with double tower and single rank ropes. To test static and dynamic performance and identify bear ing capacity of the bridge,static and dynamic test were carried out. The result showed that the design of the bridge is reliable and the quality of the constru ction is perfect.
