多塔连跨悬索桥受力特性分析

Analysis of mechanical characteristics of multi-tower and suspension span bridge

跨海大桥建设的兴起,需要我们探索更大跨越能力的桥梁结构形式.本文以泰州长江公路大桥的模型为基准,计算分析了3塔4跨悬索桥及4塔3跨悬索桥,并与基准模型进行了对比.经过计算分析连跨效应对主塔、主缆、抗滑移安全、加劲梁的影响,以期对工程建设方案选取有所借鉴.

The rise of the cross sea bridge construction requires used to explore the bridge structure with greater capacity. Based on the model of Taizhou Yangtze river bridge,the paper analyzes the three span suspension bridge and the four tower three span suspension bridge,and compares them with the benchmark model.Through the calculation and analysis of the influence of the Multi-span-continuous-stiffening-girder-effect on the main tower,main cable,anti-slip safety and stiffening girder,it is expected to be used for reference in the selection of project construction plan.
