A portable tilting table for on-site tests of the friction angles of discontinuities in rock masses
Download1992
A portable tilting table can determine the friction angles of smooth surfaces of discontinuities for the assessment of rock slope stability. The lower bound of tests on sandstones is close to the upper bound of results from surfaces lapped with #80 grit, which give basic friction angles....

Basic friction angles of the Paleozoic carbonate rocks of Kananaskis Country, west of Calgary, Canada were determined on a tilting table to range from 21.5° to 41.3°. The basic friction angles of carbonate rocks with impurity contents under 10% increase with calcite content and grain size. Clay...
