摘　　要：上第三系红黏土地层,其工程性质复杂,组成物质和相变较大,在实际开挖施工过程中,N_2红黏土隧洞易发生塌方和大变形,严重影响隧洞掘进和围岩稳定。通过对引黄入晋工程的上第三系红黏土的结构、构造及工程性质研究,分析其变形及破坏的特征,对围岩变形及塌方洞段提出了合理的工程处理措施,效果较为显著,可作为类似工程设计和施工的参考。The Tertiary red clay stratum is complicated in engineering properties and great in phase change.In the course of actual excavation,N2 red clay tunnel is prone to collapse and large deformation which seriously affects the tunneling and stability of surrounding rock.By studying the structure,construction and engineering properties of the Tertiary red clay of the Yellow River Diversion Project,and analyzing the deformation and failure characteristics,treatment measures are put forward to the deformed and collapsed tunnel section and the results are obvious which can be used as reference for design and construction of similar projects.
