摘　　要：文中借鉴顺序输送环道设计的有关经验,利用相似原理,设计了一个采用多种环道结构和元件的实验平台。该设计根据实际事故情况设置泄漏孔形状等边界条件,可最大限度模拟实际泄漏事故过程,研究各运行工况下管道破损处的出流特性和扩散规律,为泄漏量预测、泄漏后停泵方案优化等提供依据。Based on the experience of designing experimental loop for sequential transportation, an experimental platform u-sing a variety of loop structures and components was designed which utilized similar principle. The boundary conditions such asthe shape of the leak hole were set according to the actual leak accident situation. This design can simulate the actual leakage ac-cident process to the maximum extent and explore the outflow characteristics and diffusion rules under a variety of operating con-ditions. The result can provide a basis for the prediction of the leakage quantity and the pumping program optimization after theleakage happening.
