摘　　要：近年来独柱墩桥梁倾覆倒塌事故时有发生,从桥梁倾覆的机理分析,依据《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG 3362—2018)对于桥梁抗倾覆稳定性验算方法,通过对不同联长、跨径组合和独柱墩个数的桥梁分别进行空间杆系建模计算,得到独柱墩布置数量与抗倾覆稳定性验算的关联规律。In recent years,the overturning and collapse accidents of single-column pier bridges have occurred from time to time.By analyzing the mechanism of bridge overturning,according to the checking calculation method of bridge overturning stability in《Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts》(JTG 3362—2018),through the modeling and calculation of spatial member system for bridges with different connection length,span combination and number of single column piers,the correlation law between the number of single column piers and the calculation of anti-overturning stability is obtained.
