GROUND VIBRATION CHARACTERISTICS OF A HIGH FILL SLOPE INDUCED BY BLASTING

Based on the tests and measurements at a high fill slope site, this paper utilizes the ng frequency spectrum analysis method and examines the characters and basic regular about how the blasting waves transmit in slope. The dynamic response of the fill slope is further analyzed with the modal superposition of finite-element method. Based on the two analysis methods, the damaged mode, the acceleration and displacement regulars of the slope surface are characterized.
