摘要:
斜靠式异型拱桥是一种新型的、特点鲜明的空间组合结构体系,以韩江北桥为例,介绍了多跨连续斜靠式异型拱桥桥型的设计与布置,分析了桥梁结构的体系特点,通过平面和空间的静力计算,表明全桥结构设计受力合理,拱截面、吊杆、系杆、V撑箱梁混凝土应力储备适中,各跨位移均满足规范要求;主桥动力结构分析计算A,B,C三跨结构面内、外刚度接近,对第1阶失稳模态求解临界荷载比例因子计算结果为稳定系数均大于5,结构发生一类失稳的可能性较小,空间稳定性亦满足要求.
Abstract:
Taking Hanjiang North Bridge as an example, the design and arrangement of multi-span continuous reclining special-shaped arch bridge is introduced, the system characteristics of the bridge structure are analyzed, and the static calculation of plane and space shows that the design of the whole bridge structure is reasonable, the concrete stress reserve of arch section, boom, tie rod and V-brace box girder is moderate, and each span displacement meets the specification requirements. The dynamic structure analysis of the main bridge is close to the internal and external stiffness of the A, B, and C three-span structures, and the calculation results of the critical load scale factor for solving the first-order instability mode show that the stability coefficient is greater than 1, the possibility of first-class instability of the structure is small, and the spatial stability also meets the requirements.
