摘要
从协作体系的结构状态和一些重要的设计参数着手,研究多跨连续独塔斜拉协作体系桥梁的塔、梁、索受力特征及位移形态,分析主跨无索区长度、主梁高跨比、主边跨比及塔的高跨比等设计参数变化对结构所产生的影响,并提出合理的取值范围。
Based on cooperative structural system and several important design parameter, a research of continuous span single pylon cable stayed bridge cooperative system is done for bridge tower,girder and cable force resistance-displacement characteristic. The analysis was done for main girder unsupported span, depth-span ratio of girder, main-side span ratio, pylon height to girder span ratio, etc. to see how the changes in design parameter will affect the structure. At last a reasonable value range is proposed.
