摘　　要：斜拉桥的成桥状态的确定是斜拉桥设计工作中最重要的一个环节,成桥状态的合理性是保证斜拉桥结构安全、经济合理的重要前提。介绍了使用MIADS程序对斜拉桥成桥索力进行优化的方法,这个方法概念明确、简便易行、容易使设计者掌握和实际应用。The cable - stayed bridge state is very important aspect for the design of cable - stayed bridge. The rationality of the state is an important prerequisite to ensure the structural safety and economy of cable - stayed bridge. This paper introduce MIADS software how to optimize the cable forces of cable - stayed bridge. The concept of this method is a clear, user - friendly and designer is easy to used.

关 键 词：斜拉桥 成桥状态 最优索力 最小弯曲能量法
