AN EVALUATION OF A SLOPE STABILITY IN THE VECTORGRAPH METHOD

The Vectorgraph Method is a method for evaluating the stability of a slope based on the relationship between structural planes, angles of internal friction of the rock or structural planes and the plane of the slope. Besides the structural plane ( blind structural plane), the fracture structural plane caused by lateral stress should be considered in the evaluation with the vectorgraph method. This paper recommended a new simply method to evaluate the slope stability by discussing three different conditions.
