WebIntroduction. Columnar joint is a primary tensile-fracture structure with polygonal columnar shape, which is widely developed in basalt [1–3].Columnar jointed rock mass (CJRM) exhibits distinct characteristics of discontinuity, nonlinearity, heterogeneity and anisotropy, resulting in poor integrity and mechanical properties [4–7].With the development of …
WebShort on the Q-system . The Q-system for rock mass classification, developed at the Norwegian Geotechnical Institute (NGI) in 1974, originally included a little more than 200 tunnel case histories, mainly from Scandinavia (Barton et al., 1974). In 1993 the system was updated to include more than 1000 cases (Grimstad and Barton, 1993). fifth third bank mtg clause and addressWebSlope Mass Rating (SMR) is a widely used rock mass classification intended to characterize and classify rocky slopes.
