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。
Starting with the structural state and some important design parameters of the collaborative system, the mechanical characteristics of tower, beam, cable and displacement of multi-span continuous single-pylon cable-stayed bridge are studied. The main span length, The main span ratio and the high span ratio of the tower and other design parameters on the structure of the impact and propose a reasonable range of values.
