Abstract
Allowable level of blasting vibration for earth retaining wall was examined in this study. Blasting vibration was measured at near field blasting to evaluate the influence of the blasting work to earth retaining wall and rear ground. Although small scale blasting with $0.5{\sim}2.0kg$ explosives per round merely influenced to the structure and ground, but it was suggested to blast at the distance of twice the least burden considering the block movement.
