Combining with the engineering example at Mawei Avenue,the paper adopts the beam-arch combined stress mechanism,introduces the design points for the main beam,hollow-spandrel section and pier structure,analyzes the static features and seismic performance of the bridge by adopting Midas/ Civil and ANSYS,and proves the structural design is reasonable,so it accumulates some experience for similar bridges.%结合马尾大桥工程实例，利用梁—拱组合受力机制，介绍了主梁、空腹段及桥墩构造等设计要点，并通过 Midas／ Civil，AN-SYS 等软件，对桥梁的静力特性与抗震能力进行了分析，充分证明结构设计的合理，为同类型桥梁的设计积累了经验。
