摘　　要：黑山Smokovac—Matesevo高速公路项目采用欧洲标准,该项目多数隧道位于复理石中,其隧道围岩分级采用Bieniawski的RMR法围岩分级法。复理石地层特点是薄层状、岩性种类多,性质变化大等。为了进行复理石隧道围岩的准确分级,因而对该项目复理石地层隧道的RMR法分级的岩石特征参数取值进行分析。Montenegro Smokovac--Matesevo highway project uses European standard, located in flysch stratum, Bieniawski RMR method is used for the tunnel surrounding features of Flysch stratum are thin layer, multiple lithological species, great changes most of the tunnels are rock classification. The of nature, etc. In this paper, in order to classify accurately the surrounding rock, the value of characteristic parameters for the surrounding rock classification by RMR method of flysch tunnel is analyzed.
