地震作用下，桥梁上部结构之间由于发生碰撞从而导致破坏的情况越来越多。简述了桥梁上部结构之间地震作用碰撞的理论模拟方法：主要有恢复系数法、拉格朗日乘子法、接触单元法三种。其中接触单元法又包括线性弹簧模型、 Kelvin模型、等效Kelvin模型、改进的Kelvin模型、 Hertz模型、 Hertz-damp模型、三维接触-摩擦模型及非线性粘弹性模型。通过理论分析对比各种碰撞模型的优缺点、适用范围等，并且总结了影响碰撞的因素。

Lots phenomena of pounding damage between the superstructures of the bridge occurred in the earthquake. Lots of models used to simulate impact effect between bridge superstructures are presented, which include impact-restitution method, Lagrange multiplier method and contact-element method. The contact-element method includes the linear spring model, Kelvin model, equivalent Kelvin model, updated Kelvin model, Hertz model, Hertz-damp model, 3D contact-friction model and nonlinear viscoelastic model. The advantages, disadvantages and application scope of various models are compared. And the influence factors of pounding are summarized.
