摘　　要：从对结构受力合理的目的出发,论述了预应力混凝土连续弯桥制动墩的选择、支承横向偏心位置的调整及释放部分水平约束对曲线梁桥内力的影响,并结合工程实例进行分析,其分析结果对预应力混凝土连续弯桥的支座布置设计有一定的指导意义。According to the target of reasonable structure stress, the article discusses the selection of the braking pier for the prestressed concrete continuous curved bridge, the adjustment of supporting lateral eccentric position, and the releasing of the influence of partial level constraint on the inner force of curved girder bridge, and analyzes its engineering cases. The analysis result provides the certain guidance significance for the support layout and design of prestressed concrete continuous curved bridge.
