%X Based on the X. Zeng and R. S. Steedmans rotation block method,the dynamic stability analysis of gravity retaining walls under blast-induced vibration is conducted. The relationship among the earth acceleration,vibration frequency and the displacement of gravity walls is discussed. The sensitive character of the acceleration threshold to the parameters of gravity walls is studied. Taking account of the accumulated deformation under repeated blast-induced vibration and the site measured data,the earth velocity threshold is estimated. A blasting engineering example shows that the gravity retaining wall is safety,if the blast-induced vibration velocity is lower than the velocity threshold.
