| 摘 要： | 在对既有确定斜拉桥合理成桥索力方法分析的基础上,给出了最优成桥状态的判别准则,并提出了一种新的斜拉桥合理成桥索力确定方法——基于多约束条件下的最小能量法.该方法考虑因素较为全面,优化判别准则具有明确的工程含义,实施计算效率较高.实际工程运用证明了该方法的有效性和可靠性.

| Abstract: | Based on the analysis of all kinds of former methods to decide the rational completed stage cable force,a new method based on the rule of optimization of completed stage is proposed.The method is based on minimum energy method with multi-restrictions which can include more restrictions such as force,displacement and stress,etc.The rule of optimization is of specific engineering meaning and its calculation efficiency is high.The method has been applied in practical cable-stayed bridge engineering.The analysi... |
