【摘要】：人行柔性悬索桥是景区以及山区跨(河流、不良地质、峡谷)的首选桥型,柔性悬索桥发挥了高强度缆索受拉强度大的特性,可以依靠缆索支承大跨度的桥面结构和体系,桥梁施工受环境影响小,桥型造型简洁美观,桥面系加工方便,跨度设置大等优点,成为人们常说的“桥梁皇后”。本文通过对人行悬索桥主体结构(桥塔、锚碇、缆索、吊杆、索夹、索鞍、桥面系、)组成和力学特征的阐述,对人行悬索桥的总体设计和结构设计详细进行了解说。论文用实际工程设计浩然河1-49m人行悬索桥为案例进行分析,清晰列明了人行悬索桥主要设计内容和控制要点,主要构件计算用力学手工计算并用有限元分析软件MIDAS计算为有益补充和复核,验证了计算的可靠性和正确性。图纸经过武汉勘察设计协会评审,满足国家规范相关要求,并已经施工完成。
[Abstract]:Flexible suspension bridge is the preferred type of bridge in scenic area and mountainous area (river, bad geology, canyon). Flexible suspension bridge plays the characteristics of high strength cable tensile strength, and can rely on cable to support long-span bridge deck structure and system. The bridge construction is less affected by the environment, the shape of the bridge is simple and beautiful, the bridge deck system is convenient to process, and the span is large, so it has become the "bridge queen". In this paper, the composition and mechanical characteristics of the main structure (tower, Anchorage, cable, suspension rod, cable clamp, cable saddle, bridge deck system) of the pedestrian suspension bridge are expounded, and the overall design and structural design of the suspension bridge are discussed in detail. In this paper, the actual engineering design of Haoran River 1-49m pedestrian suspension bridge is used as a case study, and the main design contents and control points of the bridge are clearly listed. The calculation of the main components is done manually by mechanics and by the finite element analysis software Midas. The reliability and correctness of the calculation are verified. The drawings have been reviewed by Wuhan Prospecting and Design Association to meet the relevant requirements of the national code and have been completed.
