摘要
以龙琅高速公路车田江大桥为工程背景,建立了钢箱提篮拱桥缆塔扣塔一体化的吊装结构体系,通过有限元计算模型,分析了该结构体系在施工过程中的刚度、强度及稳定性。结果表明,该索塔结构受力符合规范要求。
Taking Chetianjiang Bridge of Longtang-Langtang Expressway as engineering background,this paper establishes the integrated hoisting structure system of cable tower and buckle tower of steel box basket arch bridge.Through the finite element calculation model,the stiffness,strength and stability of the structure system in the construction process are analyzed.The results show that the stress of the cable tower structure meets the requirements of the code.
