摘　　要：根据桥墩在多跨简支梁或连续梁桥上、下部结构体系中的刚度贡献确定墩柱的约束状态,采用欧拉理论的临时荷载稳定方程求解桥墩的计算长度。实桥算例表明,计算结果在合理范围内。这种计算方法可以获得较准确的计算长度,有关经验可供相关专业人员参考。Based on the rigidity of the piers for the multi-span simple-supported beam or in the superstructure and substructure systems of the continuous beam bridge,it is to determine the restricting status of pier pole.The temporary load stabilizing equation in Ola theory is used to solve the calculation length of pier.The example of calculating the practical bridge makes clear that the calculation result is within the reasonable range.This calculation method can achieve the more correct calculation length.The relative experience can be referred for the relevant professional members.
