为了研究支座布置形式对异型曲线钢箱梁桥支座水平反力的影响、提出对结构有利的支承布置方式，以一实际的异型曲线钢箱梁桥为例，采用有限元法建立精细的空间有限元模型，分析其在自重、二期恒载、温度作用和汽车活载等荷载下10种支座布置方式产生的支座水平反力。通过综合分析，提出较合理的支承布置方式，减小支座的水平反力，保证结构的安全使用，为类似异型桥梁的支座设计提供依据。

This paper studies the bearing arrangement of special-shaped curved steel box girder bridge,support horizontal force is put forward on the bearing arrangement structure favorable.Taking special-shaped curved steel box girder bridge with a practical example,a finite element model is built fine by the finite element method,analysis of the support level produces 10 kinds of bearing arrangement in the weight,two dead load,temperature effect and vehicle load,load force.Through comprehensive a-nalysis,the support arrangement proposed can reduce the level of support force,ensure the safe use of the structure,and provide the basis for the design of support similar shaped bridge.
