摘　　要：公路桥梁板式橡胶支座的形状系数直接决定了抗压弹性模量标准值,通过对标准全规格系列的计算分析可以看出:由于形状系数的变化导致了抗压弹性模量变化较大且变化不均衡,给橡胶支座的生产和使用带来了问题。The shape coefficient of the plate rubber bearing of the highway bridge directly determines the standard value of the compressive elastic modulus.Through the calculation and analysis of the standard fullspec series,it can be seen that the change in the shape coefficient causes a large and uneven change in the compressive elastic modulus,which brings problems to the production and use of the rubber bearing.

关 键 词：板式橡胶支座 形状系数 抗压弹性模量
