砼重力坝受冲击波荷载作用下的动力反应

Dynamic Response of Concrete Gravity Dams under Action of Shock Waves

用平面问题有限元的振型组合法和逐步积分法计算两种模型坝体受水中或空气冲击波荷载作用的动力反应,其成果与试验成果一致,很好的反映了模型坝体在冲击波荷载作用下的动力反应。

Method of vibration mode combination and method of successive integration of plain problem FEM were used to calculate the dynamic response of two modelled dams under the action of shock waves in water and in air. Results calculated are in good coincidence with those tested, reflecting satisfactorily the dynamic response of modelled dams under the action of shock waves.
