摘　　要：该文以达陕高速泥溪沟2号大桥——曲线连续刚构桥为工程依托,建立该大桥的三维板单元模型。通过对计算数据的分析,得到预应力钢束对不同曲线半径连续刚构桥梁的变形以及受力的影响,并且总结了相应的变化规律,为今后此类桥梁的设计与施工提供参考。Based on curved continuous frame bridge, a three-dimensional plate element model of the bridge is set. The authors analyze the effect of pre- stressing tendon on the transform and internal forces of curved continuous frame bridges with different radius and summarize relevant changing rules. This can provide some reference for the design and construction of such kind of bridge.
