| 摘 要： | 以预应力混凝土矮塔斜拉桥为对象,基于影响矩阵方法进行了成桥状态优化分析,讨论了索力对于成桥结构内力分布的影响,研究结果表明,索力对于小跨度的矮塔斜拉桥主梁弯矩等内力分布影响较大,在大桥建设过程中应该充分考虑,以保证大桥运营的安全性和耐久性。

| Abstract: | Prestressed concrete cable-stayed bridge in the object extradosed,based on the influence matrix method into the bridge state optimization analysis,the influence of cable force into the bridge structure for the internal force distribution. The results show,for small cable tension tower cable-stayed span dwarf main beam bending moments force distribution greater impact in the process of building the bridge should be fully considered to ensure the safety and durability of bridge. |
