The impact compressional tests of Bukit Timah granite of Singapore were conducted using a light gas gun. The plane stress waves were observed in the sample and polynomial equation representing propagation and attenuation law under the state of one-dimensional strain in the granite is obtained by regression of the experimental data. The attenuation rate η of stress peak is discussed and the attenuation indexes α within different stress range are given.
