Study on Surrounding Rock Classification of Railway Tunnel with HiPParion Laterite Stratum in West Piedmont of Lvliang Mountain
摘要
Abstract
The Hipparion laterite stratum in west piedmont of Lvliang Mountain is characterized by thick deposition, good continuity and lots of type sections, and has always been the research hotspot of Hipparion laterite. But, the study on its engineering geology features and geo-mechanics properties still remains very weak. So, surrounding rock classification in Hipparion laterite stratum is a new geological question faced by tunnel construction of Lvliang section of Middle and Southern Shanxi Railway project. Based on on-site monitoring, laboratory test and practical experience, this study researched the physical and mechanical indexes and strength property of Hipparion laterite, and analyzed relevant effects on Hipparion-laterite surrounding rock stability, including the underground water effect, fissuring effect, sandy soil interlayer effect, and the coupling effect of various factors. Finally, this study quantitatively discussed how to class the Hipparion-laterite surrounding rocks respectively under the conditions of homogeneity and multiple factors.关键词
