| 摘 要： | 钢管-钢管混凝土拱桥是最近提出的一种较新型的结构形式，其受力性能和传统的钢管混凝土拱桥和钢管拱桥有很大的不同。拱肋内倾角和拱脚混凝土灌注高度是钢管-钢管混凝土提篮拱设计中的两个重要参数，他们对于成桥结构的内力、稳定和动力特性都有很大的影响。文中借助通用有限元程序，基于一座跨径150m的中承式钢管-钢管混凝土复合提篮拱，对以上影响因素进行了分析。

| Abstract: | Steel tube & concrete-filled steel tube arch bridge is a newstructural style proposed recently,it is greatly differential with traditional concrete-filled tube arch bridges in performance.The inclination angle of arch rib and the height of concrete-spouting at the arch springing are two important parameters in the design of Steel tube & Con-crete-filled steel tube X arch bridge,they greatly influence the performance of the structure in stable properties and dynamic characteristics.This article analyses the influences proposed above via a150spanned arch bridge. |
