摘　　要：位于U形峡谷的西宁河大桥是采用缆索吊装施工的拱桥。根据不同的地质条件,其锚碇系统设计成前置式锚梁及锚碇桩与永久结构桥台组合受力。利用数值分析方法对该桥整体结构进行验证,验证结果表明,其具有安全、经济、可靠的使用效果。The Xining River Bridge is an arch bridge that is located in U-shaped gorge and constructed by means of cable hoisting. In accordance with different geological conditions,its anchor system is designed in the form of stress on combination of front-loading anchor beams and anchorage pile with permanent structure abutments. This paper verifies its whole structure of the bridge by means of the method of numerical analysis,and the results of verification show that the structure exhibits high safety,economy and reliability in use.
