摘　　要：V形刚构桥墩结构抗推刚度较大,温度、收缩徐变引起的附加内力使桥墩存在较大弯曲内力。为考察结构安全,采用ANSYS建立V形刚构墩-梁固结区有限元模型。选取自施工到成桥最不利工况进行静力强度分析,得到各工况作用下的应力分布。分析结构应力水平,对结构安全进行评价,并对配筋作出改进。Since the anti push rigidity of V type bridge pier is larger, additional internal forces genera ted by temperature, shrinkage and creep lead to a larger bending moment in the pier. In order to inves tigate the structural safety, the FEM model of the fixation part of pier pylon beam of the V type pieris established by using ANSYS. The most unfavorable working conditions is selected to analyze the star ic strength. The result of its stress distributions can be obtained and structural strength can be corn prehensively evaluated according to the stress cloud. By analyzing structural stress levels, the struc rural safety is evaluated, and the reinforcement is improved.
