二滩水电站在导流隧洞堵头设计中，以模型试验、计算成果为基础，并结合国内外采用的设计原则和工程实例，对堵头的工作状态、合理长度、破坏机理等进行了较深入的研究，提出“围压握裹”概念，探讨既有足够的安全性，又有利于取得缩短工期和减少工程造价综合效益的堵头设计准则，取得了有启发意义的成果。 Ertan Hydropower Station in the diversion tunnel plug design, based on the model test and calculation results, combined with the design principles and engineering examples used at home and abroad, the working status of the plug, the reasonable length, the failure mechanism were more in-depth The author puts forward the concept of “confining pressure wrap”, explores the design criteria of plugs which not only has enough safety but also shortens the construction period and reduces the construction cost comprehensive benefits, and achieves inspiring results.
