摘要
茅草街大桥为主跨368 m的自锚中承式钢管混凝土拱桥,在同类型桥型中跨度最大。主拱拱肋采用三跨缆索吊吊装施工,技术含量高,施工难度大,实践表明,茅草街大桥钢管拱肋缆索吊装施工较为成功,其经验值得为同类型桥梁施工借鉴。
The Maocaojie Great Bridge is a middle-support-style concrete-filled steel tubular arch bridge with a main span of 368 m ; it is currently the longest span bridge of its kind bridges. The main arch rib adopts three spans cable hoists to lifting and elevating,the technique content is very high and great difficulties have been overcome in the construction, the construction is proved to be successful by practice and worth spreading and referring for other similar bridges.
