摘要
柔性人行悬索桥具有桥面系构造简单、耗钢量低、桥梁架设和维护方便、桥型美观以及造价低等优点,它能够充分发挥高强钢丝绳抗拉强度大的特点,不需要特别高的桥塔,就可以架设大跨度的桥梁。这种桥型是旅游景点和交通不便的山区较为理想选择的桥型。广元市处于龙门山、米仓山与四川盆地低山的接合地区,地势北高南低,地形起伏大,由于广元地区特殊的地质条件,在该地区修建其他桥型如连续梁桥或拱桥不仅难度大、而且造价也很高,相对而言,与同跨径的其他桥型相比较,选择结构型式简易应川的人行悬索桥则是一种比较经济、可行的方案。
     本文首先介绍了在进行人行悬索桥桥址选择时的主要内容,包括社会可行性调研和技术调研;其次,讨论了人行悬索桥设计的主要内容,包括修建人行悬索桥的材料,设计荷载,结构分析及设计等;最后本文采用非线性的有限元理论,将大跨度悬索桥的设计思想与柔性人行悬索桥的设计思想结合起来,运用大型有限元软件Ansys对120m人行悬索桥结构进行了静力分析、动力分析以及非线性分析。在静力分析中,主要探讨了柔性悬索桥的内力和变形控制,最终提出在进行结构设计时需要考虑风荷载的影响且需要设置如风缆等构造措施以抵抗风荷载对结构受力的不利影响。对于动力分析,主要探讨了这种桥型的抗震性能,采用反应谱法对结构进行了动力响应分析,得出塔墩固结体系的人行悬索桥结构采用塔身横桥向内倾且塔柱间设置中横梁的桥塔来抵抗地震对结构的不利影响。最后对结构进行了极限承载力分析,在整个分析过程中,桥塔一直处于弹性受压状态,主缆的极限荷载安全系数为1.08,说明结构的承载能力能够满足要求。
     本文的最终目的是基于结构安全性、适用性、经济性和美观性的基础上,充分发挥柔性人行悬索桥的优点,为人行悬索桥的发展开拓新的领域。
Pedestrain suspension bridge structure has the concise deck. It consumes less steel products and can be easy builded and maintained. Its model is beautiful and the construction cost is low. The bridge structure can fully exert the characteristic of the high-strength steelwires which can bear greatly high tension. Such bridge has been more ideal structure system in tourist area and mountains where is poor in traffic. Guangyuan city stands at the junction of Longmen mountains, Micang mountains and low mountains of the Sichuan basin region. Its terrain is high in north and low in south, and big undulating also. To construct other bridge-types like continuous bridge or arched bridge not only difficult, but cost is also high for the special geological conditions in Guangyuan region. Relatively, It's more economical and feasible solution to choose the type of pedestrain suspension bridge relative to the same span of other bridge-types.
     Firstly, this article introduces the main contents during the pedestrain suspension bridge site selection, including social feasibility survey and technical survey. Secondly, this article discusses the main contents about pedestrain suspension bridge design, including building materials, design load, structural analysis and design, etc.; Finally, this article uses non-linear finite element theory, and unites the design methods of long-span suspension bridge and pedestrain suspension bridge. This article uses large-scale finite element software Ansys for structural static analysis, dynamic analysis and non-linear analysis. In the static anslysis, the article mainly discusses the internal force and deformation control, and finally proposed the impact of wind loads during structural design and setting structural measures such as wind cables to counteract the adverse effects of the force by wind load. Regarding the dynamic analysis, this article mainly discusses the earthquake resistant behavior of this bridge-type, useing response spectrum methods to analyses dynamic response of pedestrain suspension bridge, in order to resist the adverse effects of earthquakes on structures the type of tower which the pylon cross-bridge tilts inward and setting middle cross beam has been proposed. Finally, this article conductes the ultimate load bearing capacity anaylsis of pedestrain suspension bridge, throughout the analysis process, the towers has been in a state of elastic compression, the ultimate load bearing capacity safety factor of main cable is 1.08, which indicated that the capacityof the structure meets the requirements.
     The high aspiration is that this article can fully exert the merits of suspension foorbridge and develop the new domain of the development in pedestrain suspension bridge based on satitsfing security, applicability, economy and artistry.
