By optimizing the experimental program

the cement sample inner damage by exploding wave in water is realized; and the phenomenon of shear damage and tensile damage by exploding wave are observed. The piezoelectric transducer

which can be used to measure the pressure or velocity of the exploding wave

is designed

manufactured and calibrated. The wave shape gained from self-designed transducer in water is compared with it of commercial transducer

and the result shows that the wave shapes coincide with each other well and the dimensions of the transducer can meet the need of the experiment. The exploding wave pressure in the cement sample is measured and compared with the pressure calculated by the model from the dimensional analysis; and the result shows that the pressure calculated by the model is 5 %—15 % higher than it measured in the experiment.
