Abstract
Numerical evaluation of the effect of blast induced vibration on adjacent structures requires determination of the damping ratio. Selection of the dampring ratio for the rock mass is very difficult because it is heavily influenced by the joint layout. We propose a simple yet robust method to estimate the damping ratio of rock mass that fits the target attenuation curve. The damping ratio can be selected as functions of the shear wave velocity of the rock mass and the attenuation parameter of the target attenuation relationship.
