摘要
云贵高原是喀斯特地貌分布较广的地区,且类型较多,喀斯特地貌产生的主要条件是存在碳酸盐类岩石,云南省昭通市彝良地区石灰岩分布广泛,高速公路隧道施工均会遇到不同类型的岩溶地质,给地下工程施工带来很多不利影响,如何在岩溶区进行隧道施工,成了岩溶地区高速公路施工面临的重要问题,研究岩溶区隧道施工对岩溶区高速公路建设意义重大。
Yunnan-Guizhou Plateau is a widely distributed area of Karst Geomorphy with many types. The main condition for Karst Geomorphy is the presence of carbonate rocks. Limestone is widely distributed in Yiliang area of Zhaotong City, Yunnan Province. Different types of karst geology will be encountered in the construction of Expressway tunnel, which brings many adverse effects to the construction of underground works. How to carry out tunnel construction in karst area has become an important problem faced by expressway construction in Karst area. It is of great significance to study tunnel construction in karst area for Expressway Construction in Karst area.
