矮塔斜拉桥成桥状态优化分析

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。%Prestressed concrete cable-stayed bridge in the object extradosed,based on the influence matrix method into the bridge state ootimiza-tion 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 soan dwarf main beam bending moments force distribution greater imoact in the orocess of building the bridge should be fully considered to ensure the safety and durability of bridge.
