摘　　要：结合某高速公路岔道口桥梁的实际情况,应用大型有限元MIDAS软件建立岔道口桥梁的梁格空间模型对岔道口受力进行仿真分析,并运用ANSYS软件建立实体模型与梁格模型在自重情况下的结果进行对比,根据应力分布特点对结构进行配筋研究,取得了传统平面计算无法获得的结果。Combined with the practical situation of one highway fork bridge, this paper establishes the beam-grid model of the bridge to carry out simulation analysis by using MIDAS software. The threedimensional solid model is established by using ANSYS software to calculate stress distribution of the highway fork bridge under self-weight. According to the characteristics of the stress distribution, reinforcement research is carried out and the results gained cannot be taken from conventional plane calculation methods.
