摘要:
悬索管桥具有比传统悬索路桥柔性大、阻尼低、频谱不均匀、自重轻、横向刚度小等的典型特性,动力学行为复杂,更容易引起结构失效和破坏。文中以漾濞江油气集输悬索管桥为研究对象,基于Midas软件建立了地震载荷条件下的悬索管桥有限元模型,开展了悬索管桥的地震响应、抗震性能数值模拟研究,揭示了管桥体系的危险区域和可能存在的破坏形式,发现:合理设置吊杆和拉索分布密度,对悬索桥自身的抗震有利。根据相似原理,搭建了漾濞江悬索管桥的室内实验系统,探究悬索桥动力特性及结构参数对动力特性的影响规律,验证了数值模拟正确性,为漾濞江油气集输悬索管桥的抗震性能设计提供理论指导。
Abstract:
Compared with the traditional suspension bridge, the suspension pipe bridge has the typical characteristics of large flexibility, low damping, uneven frequency spectrum, light self weight, small lateral stiffness, etc. the dynamic behavior of the suspension pipe bridge is complex, which is more likely to cause structural failure and damage. This paper takes Yang bi river oil and gas gathering and transportation suspension pipe bridge as the research object. Based on MIDAS software, the finite element model of the suspension pipe bridge under seismic load is established, carries out the numerical simulation research of the seismic response and seismic performance of the suspension pipe bridge, reveals the dangerous area and the possible failure form of the pipe bridge system, and finds that: reasonable setting of suspender and cable distribution density is beneficial to the seismic resistance of the suspension bridge itself. According to the similarity principle, the indoor experiment system of Yangbi River suspension pipe bridge is built to explore the influence of dynamic characteristics and structural parameters on dynamic characteristics of suspension bridge, verify the correctness of numerical simulation, and it provides theoretical guidance for the seismic performance design of Yangbi river oil and gas gathering and transportation suspension pipe bridge.
