摘　　要：以山西省长治市神农湖大桥为例,介绍独塔斜拉桥的总体设计思路及主要构件,包括索塔、索塔锚固系统、主梁、斜拉索;并对主桥整体和索塔锚固系统进行静力分析。结果表明,主桥整体结构在成桥状态和施工阶段均满足规范要求,且索塔锚固系统设计合理。研究成果可为同类桥梁的设计、计算提供建议和参考。Taking the Shennong Lake Bridge in Changzhi,Shanxi Province as an example,it introduces the overall design ideas&main components of a single-tower cable-stayed bridge,including pylons,pylon anchoring systems,main beams and stayed cables;the static analysis of the whole main bridge and the cable tower anchorage system is carried out.The results show that the overall structure of the main bridge meets the requirements of the specification in the completed state&construction stage,and the cable tower anchoring system is designed reasonably.The research results can provide suggestions&references for the design&calculation of similar bridges.
