Computation and Analysis of High Rocky Slope Safety in a Water Conservancy Project

Table 2

Slope geological model for rock mass.

Order	Grading standard	Geological type and property	Geological evaluation
I	Fault with greater than 1000 m extension length and greater than 0.5 m broken band width	Weak structure plane; continuous distribution throughout the bank and both sides	It controlled the boundary of the whole slope stability
II	100 m~1000 m extension length and 0.2~0.5 m broken band width	Weak structural plane; not completely cutting the slope	It controlled the potential weak surface; weak surface affected rock strength and deformation
III	Fault and the growing crack with less than 100 m extension length and less than 0.5 m broken zone width	Rigid structural plane; fault filled with rock fragments and breccias; crack filled with calcite	It influenced the integrity and the overall strength of the rock mass
