摘　　要：曲线匝道的小跨径连续箱梁桥桥墩单支点设计易存在支座脱空现象,影响桥梁的整体安全,需对结构进行抗倾覆性的验算,保证桥梁的安全性。The design for single supporting point of small - span continuous box girder bridge pier of curved ramp has a phenomenon of bearing separation, which can influence the whole safety of the bridge. Therefore, the check calculation on the overturning resistance of the structure needs to be performed, so as to guarantee the safety of the bridge.

关 键 词：曲线桥 抗倾覆 支座脱空
