摘　　要：苏丹跨河栈桥为重要的临时工程结构,具有半永久性的特点,桥上安装带式输送机输送矿石,所处环境高温、多雨、大风、地震等,是我国尚无专用设计标准的工程,对设计的栈桥结构进行了优化计算,结果表明,该处理方案取得了较好的技术经济效果,为栈桥设计提供了理论基础。The Sudan large-span trestle is an important temporary engineering structure,with semi-permanent characteristics. The trestle is mounted with the belt conveyer for conveying the mineral in a high-temperature,rainy,windy area with earthquake occurrence. Since there is no special design standard for the engineering currently,the paper introduces the optimization calculation for the designed trestle structures. The result shows that the program brings good technical and economic effects,providing theoretic foundation for designing the trestle.

关 键 词：大跨度栈桥 连续桁架 优化设计
