It is known that there are many large-scale deep-seated rock slope failures mostly induced by earthquakes (Fig. 1).Some of them are Oya-kuzure by 1707 Hoei earthquake, the Dadu River landslide by 1786 Shichuan earthquake, Mayuyama mountain failure caused by 1792 Unzen earthquake, Neodani rock slope failures by the 1891 Nobi-beya earthquake, Usoi slope …
Intact rock strength . The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well -known point load strength index can be useful as the
Effective rock size required for riverbank stabilization under applied critical shear velocity: V c = critical mean flow velocity 𝑑𝑠 = stone diameter ∅ = angle of repose of riprap rock h= flow depth h/ 𝑑𝑠 =relative submergence d m = effective rock size 𝜏0 = applied shear stress 𝜏∗𝑐 = critical Shield parameter ∅1

The Hoek–Brown criterion was introduced in 1980 to provide input for the design of underground excavations in rock. The criterion now incorporates both intact rock and discontinuities, such as joints, characterized by the geological strength index (GSI), into a system designed to estimate the mechanical behaviour of typical rock masses encountered in tunnels, …
