摘　　要：以马尔代夫北马累环礁中马友谊大桥主栈桥为背景,采用MATLAB和Ansys软件建立了有限元模型,并在编程的基础上得到了基础数据,使用APDL快速得到了满足施工现场要求和使用功能的结构形式和材料参数。研究结果表明:该方法快速完成了猫道式人行悬索栈桥设计和静动力分析,较好地解决了施工现场不断调整设计以更新设计参数的问题,同时快速得到了设计计算结果,为类似工程提供了参考。Based on the main trestle of China-Malaysia Friendship Bridge in North Male Atoll of Maldives, the finite element model was established by MATLAB and Ansys software. The basic data were obtained by programming. The structural style and material parameters that could meet the requirements of construction site and service functions were quickly gotten by APDL. The results indicate that the design and static & dynamic analysis of of the catwalk pedestrian suspension trestle can be quickly completed by this method, and the problem of constantly adjusting the design to update the design parameters will be better solved on the construction site. In addition, the design calculation results can be given quickly. The method provides a reference for similar projects.
