Abstract:YBJ-1 blasting vibration self-recording system and CRAS (The random signal and vibration analysis system) software were selected to survey, analyse and deal with the signal of blasting ground vibration. A practical equation about attenuation of blasting ground vibration wave was derived and blasting according to Safe Controlling Index was suggested. Finally, the problem on blasting vibration liquefaction under the river bank was discussed.
Key words: blasting ground vibration; river bank; protection
