吊杆布置对钢管混凝土拱桥受力性能的影响

Lifted pile layout's influence on the force function of steel-tube concrete arch-bridge

通过数例分析和对比,研究了不同吊杆布置对桥梁结构静力、动力特征及稳定性的影响,同时还阐述了吊杆自身的静、动力特征与构造设计要点,对钢管混凝土拱桥的吊杆布置形式选择及设计提出了相应的建议,以促进钢管混凝土拱桥技术的全面进步。

Through analysis and comparison of examples,it researches different position of lifted pile＇s influence on the dynamics and statics features as well as the stability.Meantime,it also elaborates the pile＇s dynamics and statics features and structural design points,gives relative advice on choice and design of steel-tube concrete lifted pile layout,so as to promote the full progress of steel-tube concrete arch-bridge skills.
