摘要： 为避免堰塞湖传统引流泄洪应急处置措施导致次生 灾害的发生，提出了强射流冲击引流的新方法，简析了强射流的特 性和影响因素，计算了射流冲击力的理论数值，通过大量实地试验 和数据分析对比，验证了采用强射流冲击引流技术在堰塞湖坝体 上快速冲击形成一定规模的引流泄洪槽具有一定的可行性。强射 流冲击引流技术对迅速、有效、安全地进行堰塞湖引流泄洪，减少 人员伤亡和经济损失具有非常重要的现实意义。

Abstract: In order to avoid the secondary disasters caused by the traditional emergency measures of drainage and flood discharge, a new method of strong jet impact drainage is put forward, the characteristics and influencing factors of strong jet are analyzed, and the theoretical value of jet impact force is calculated. Through a large number of field tests and data analysis and comparison, it is verified that the strong jet impact drainage technology is used for rapid flushing on the dam body of the barrier lake. It is feasible to form a certain scale of drainage and flood discharge trough. The technology of strong jet impact drainage is of great practical significance for the rapid, effective and safe drainage of the barrier lake and the reduction of casualties and economic losses.
