IS 13365 : Part 3 : 2025 Quantitative Classification Systems of Rock Mass - Guidelines - Part 3 Determination of Slope Mass Rating

1 SCOPE

This standard (Part 3) covers the procedures for obtaining the value of slope mass rating (SMR) for preliminary assessment of the stability of rock slopes. The approach is based on modification of RMR system using adjustment factors related to discontinuity orientation with reference to slope as well as failure mode and slope excavation methods.
