人行钢管混凝土提篮拱桥受力特性及荷载试验研究

Study on the mechanical characteristics and load test of CFST basket handle arch footbridge

介绍了自平衡钢管混凝土提篮拱桥体系受力特点。以小清河菜园桥为工程实例,通过有限元分析和静动力荷载试验相结合的手段,研究该桥在设计荷载下的受力特性,并评定其承载能力。试验结果表明,该桥承载能力满足设计人群荷载的要求。

The mechanical characteristics of self- balance CFST basket handle arch bridge is introduced. Taking the Caiyuan bridge for engineering example, through finite element simulation analysis and load test, the mechanical characteristics is analyzed, and the actual bearing capacity is evaluated. The results shows that its bearing capacity is satisfied with the design of crowd load.
