斜交系杆拱桥受力特征及应用

斜交系杆拱由于受力较为复杂,在工程中较少采用,但斜交系杆拱可有效减小桥梁跨径,降低工程造价。在正、斜交系杆拱受力分析基础上,对斜交系杆拱在中小跨径桥梁中应用的可能性进行了探讨,有关经验可供相关专业人员参考。

Stress Characteristics and Application of Skewed Bowstring Arch Bridge

The skewed bowstring arch is less used in engineering because of its more complex stress,but the skewed bowstring arch can efficiently decrease the bridge span and reduce the engineering construction cost.On the basis of stress analysis of orthogonal and skewed bowstring arches,the article discusses the feasibility to use the skewed bowstring arch in the small and medium spans of bridge.The relative experience can be referred for the relative technical members.
