摘　　要：龙潭河特大桥采用连续刚构体系,其桥墩最高达178 m。针对该桥双肢薄壁墩系梁局部受力复杂的情况,运用ANSYS软件对其建立空间实体有限元模型,分析了系梁处桥墩及系梁的局部应力分布特点,为同类型结构日后的设计和施工提供参考。Longtanhe Bridge is designed as a continuous rigid-frame bridge with its highest pier up to 178 m. In the light of the complexity of local stressing conditions at tie beams of the double-shaft, thin-wall piers of the Bridge, the ANSYS software is used to establish a spatial finite element model, and to calculate and analyze the local stress distribution at the parts of the piers close to the tie beams and at the beams. The calculation and analysis results in the paper may provide reference to the design and construction of the similar structures in the future.
