| 摘 要： | 针对部分斜拉桥结构特征,研究主梁高度、索塔高度、索塔抗弯刚度、边中跨比、边中跨无索区长度等结构主要参数变化对结构各部位荷载效应的影响规律.有助于深化认识结构主要构件梁、塔、索在活载作用下的力学性能,以便预估当结构某一主要参数变化时,可能出现的情况.为设计经济、合理的结构形式提供参考.

| Abstract: | Taking into account of the properties of the partially cable stayed bridge, the influence of structural load effects arising from some main structural parameters such as height of main beam, height of towers, the bending stiffness of towers, the ratio of center span and side spans, the length without cable of side spans and center span is researched in this paper. All of these are usefull to understand the mechanics performance of the main components under the live load condition, to forecast the possible effects on the bridge when one of main parameters is changed, and to provide the reference for the economic and rational structure design. |
