研究了海底输油管道在水下爆炸气泡作用下的塑性动力响应。对管道进行了详细的流体力学分析，得到了作用在管道上的流体力。假定管道由刚性、理想塑性材料构成，得到了控制此类管道塑性动挠度的水塑性方程，并对该方程进行了解析解。给出了三个算例，讨论了塑性动力响应的特点和本文分析的适用范围。文中还给出了半管长度与最大永久塑性变形的关系。
Dynamic plastic response of a submarine oil pipeline to an underwater explosion bubble is studied in this paper. A detailed fluid-structure analysis is given to find the fluid forces acting on the pipeline. Assuming the pipeline is made from rigid, perfectly plastic material, we obtain the hydroplastic equation governing the dynamic plastic deflection of such a pipeline, The equation is analytically solved. Three examples are given to discuss the features of the dynamic plastic response and the applicability range of the present analysis. The relation between the half pipe length and maximum permanent plastic deflection is also given.
