摘要
结构体系的选择对桥梁的安全经济、美观等性能至为重要。文中结合某实际工程,对部分斜拉桥不同结构体系的受力性能进行对比分析。在墩高受限时,塔梁固结体系各方性能较好,为降低主墩刚度,提出了墩身切片、下部结构采用钢箱-混凝土提高结构整体性能的方法,为同类桥梁的设计提供了解决思路。
The selection of structural systems is very important for the safety,the economy,and the beauty of a bridge.The mechanical properties of different structural systems of partial cable--stayed bridges are analyzed.Under the condition of limited pier height,the performance of fixed pier-tower-beam is good.To reduce the stiffness of the main pier,the method of slicing the pier body and adopting steel-concrete to improve the overall performance of the structure is proposed for the rigid system with limited pier height.The article provides a solution for the design of similar bridges.
