摘　　要：利用有限元软件对一座斜交曲线桥建立空间计算模型并进行受力计算,对其平面内位移进行了分析,阐述了斜交曲线斜拉桥产生平面位移的机理,研究了温度、混凝土收缩徐变、活载等不同类型荷载作用情况下平面内位移的变化规律,全面分析了斜交曲线斜拉桥力学特点和空间作用效应,可以作为其他斜交曲线斜拉桥设计分析的依据.A space model for a skew intersection curved bridge is established, and its stress distribution is calculated. The generation of plane displacement of skew intersection curved cablestayed bridge are introduced and the laws of plane displacement variation are studied in the cases of the bridge subjected to different loads, such as temperature, the shrinkage and creep of concrete, the living loads and so on. The stress and the space action effect of the skew intersection curved cable-stayed bridge are completely analyzed, which can be used as references for designing this type of bridges.
