摘　　要：连续刚构拱梁组合桥梁,兼有连续刚构桥刚度大与拱桥跨越能力大的优点。以某连续刚构拱桥为研究对象,应用ANSYS软件建立起该桥的三维有限元模型,研究该桥箱梁应力的横向分布规律与全桥的温度应力。Continuous-rigid-frame-arch bridges have such advantages as the high stiffness of continuous rigid-frame bridges and the stronger spanning capacity of arch bridges. This paper takes a continuous-rigid-frame-arch bridge as the object of study, and establishes its three dimensional finite element model using the software ANSYS to study the stress distribution .of the box girder in the cross direction and the thermal stresses in the bridge.

关 键 词：连续刚构拱桥 应力横向分布 温度应力
