采用有限元方法建立飞机与核电站屏蔽厂房非线性模型，利用发动机以不同速度撞击钢筋混凝土板试验验证撞击分析中飞机与核电站屏蔽厂房有限元模型非线性材料本构及参数，并分析飞机网格尺寸效应。对大型商用飞机以200m/s速度撞击核电站屏蔽厂房非线性撞击过程模拟计算及假设核电站分别为线弹性、刚性本构模型撞击过程计算。获得大型商用飞机撞击核电站屏蔽厂房的荷载时程曲线，分析飞机撞击力及核电站屏蔽厂房结构变形特点及核电站结构刚度对撞击力影响规律，并讨论在核电站初步设计中常用飞机撞击力计算方法-Riera方法的适用性。

Finite element models of reinforced concrete slab impacted by the engine at different speeds were established. Using results of those simulations, material models and related parameters were calibrated. The mesh size effect was also analyzed. A large commercial aircraft at 200m/s impacting to steel concrete nuclear power plant structure is discussed utilizing nonlinear material model, the result of the crash was analyzed compared by rigid and elastic model, regularity of aircraft impact load with different structure stiffness was proposed，and the applicability of the common method --Riera method used in aircraft impact force calculation in the preliminary design of nuclear power plant was discussed.
