钢管混凝土刚架系杆拱桥的合理形式

摘要

The properties of concrete-filled steel tubular frame tied arch bridge were studied to provide a guidance for practical engineering. Major study was conducted from the following aspects: structure distribution of internal force of concrete-filled steel tubular frame tied arch bridge under dead and live loads were studied; based on analyzing the structure parameters such as arch axis, tie force, and stiffness ratio of arch to pier etc. ,and probing into the effect law of the given parameters on the structure in ternal forces, it is found that the given structure forms had a valueable application value.%通过钢管混凝土刚架系杆拱桥受力性能的研究,为实践工程提供有利指导.主要从以下几个方面进行研究:考察钢管混凝土刚架系杆拱桥结构的受力性能,分析其在恒载、活载作用下的结构内力分布;对钢管混凝土刚架系杆拱桥结构参数,即,拱轴线、系杆力、拱墩刚度比等进行了分析,考察它们对结构内力的影响规律,具有较强的运用价值.
