摘要
紫坪铺水利工程穿越F3断层的大断面导流洞的顺利贯通是新奥法施工概念在软弱破碎围岩中的成功应用。本文较系统地介绍了导流洞穿越F。大断层时的开挖、支护技术，总结了复杂地质条件下新奥法施工的经验教训，对同类工程的施工建设有一定的工程借鉴意义。
The diversion tunnel with large cross section of Zipingpu project is runthrough by application of Neoau method successfully in excavating the tunnelin katamorphic zone. The experience and lessons on technology concerning excavation and set supporting are summarized in this paper, which could provide some reference for other similar projects.
