In order to reveal the blasting vibration propagation law of the new cast concrete,the paper designed the ultrasonic wave and blasting vibration test of the new concrete block. Test results demonstrated that the peak particle velocity(PPV)of each measuring point in 3 days increased as a whole with the increasing of the blasting time and the age. This period,there was the phenomenon of rebound after the fall of PPV in the near and middle field. But overall,after 3 days,the PPV of each measuring points decreased with the increase of blasting times,more significantly in third to fifth day than in sixth to eighth day. And with the increasing again of the blasting time,the PPV of the middle and far area had the process of sudden increase in sixth to eighth day. In the first 6 blasting,the value of K rapidly increased,and rapidly decreased. Then,with the increasing again of blasting times,K generally decreased,and the amplitude of its decrease changed from big to small. Meanwhile, increased slowly as a whole,however,existed mutations of sudden decrease. In 3 days,the ultrasonic wave velocity increased with the increase of age and the number of blasting effect. But after 3 days,its change was similar to blasting vibration velocity.
