摘要
鹧鸪山隧道是我国在建高海拔、高寒地区的长大公路隧道 ,地质情况复杂。文章介绍了隧道的地质概况和围岩特征 ,并重点阐述了隧道大坍方的情况及处理措施 ,指出了对变质岩地区碳质千枚岩围岩级别确定的重要性 ,为位于高原。
The Zhegushan tunnel under construction is a large highway tunnel located at high elevation and in a cold zone, with complex geological conditions. This paper describes the geology and characteristics of the surrounding rocks of the tunnel, and the serious collapse and its countermeasures in detail. It points out the importance to determine correctly the rock classification of carbonaceous phyllite in metamorphic rock zone. The practice can be referred to by similar projects.
