摘　　要：以一座单柱式钢筋混凝土空心板简支板桥为例,介绍考虑支座的影响与否,桥梁柱墩荷载内力的两种计算方法,并将两种计算成果加以分析和比较,从而说明桥梁支座的重要性,刚性的桥墩台加设橡胶支座后,不但有利于水平力的传递,还能吸收和阻滞温度等引起的墩台受力,为工程技术人员提供有价值的参考数字。Taking the single-column reinforced concrete simply-supported hollow slab bridge as an example, this paper introduces two calculations of the load inner force of columnar pier with or without the consideration of the bearing influence. Having the results of two calculations analyzed and compared, the importance of the bridge bearing can be illustrated. The rigid bridge pier with rubber bearing not only benefits the transfer of horizontal force, but also absorbs and impedes the loading of the pier caused by temperature, providing valuable reference for project technicians. 
