摘　　要：不对称拱桥突破了拱桥结构对称性的传统模式，作为一种新桥型，具有较好的适用性和经济效益。本文介绍了不对称拱桥的合理构造与设计计算方法，并运用MIDAS软件建立某不对称无铰空腹式拱桥进行模拟分析，总结了不对称拱桥的受力特点。Asymmetrical arch broke through the traditional mode of the symmetry structure. As a new bridge type,it has better economic efficiency and adequacy. This article introduces the reasonable structure and design calculation method of asymmetrical arch, and use MIDAS software to set up an asymmetric hingclcss arch to simulation analysis it and thereupon the features of forec bearing.
