Slope Stability Classification Systems

 

 

Classification of rock mass is another important approach to assess the engineering behaviour of a rock mass. Empirical relations between rock mass properties and the behaviour of the rock mass in relation to a particular engineering application are combined to give a method of designing engineering structures in or on a rock mass. In a classification system empirical relation between rock mass properties and the behaviour of the rock mass in relation to a particular engineering application are combined to give a method of engineering structure design. Rock mass classification has been applied successfully for many years in tunneling and underground mining. Some rock mass classification systems developed originally for underground excavations have been modified for slope stability application.

 

Classification systems in slope stability analysis

A number of classification system are available for analysis of slope stability. Some of the most commonly referred classification system are :

Slope Mass Rating (SMR)

Chinese Slope Mass Rating System (CSMR)

Rock slope rating (RSR)

Slope stability rating (SSR) classification system, and

Dump mass rating
