VERIFICATION METHOD AND VERIFICATION DEVICE FOR ELASTIC WAVE PROPAGATION CHARACTERISTICS
To provide a verification method and a verification device for elastic wave propagation characteristics that can easily and repeatedly verify the relationship between the polarity reversal of reflected waves and rock properties with high accuracy.SOLUTION: A verification method for elastic wave propagation characteristics of rock or ground comprises the steps of generating an elastic wave inside a test piece 12 formed by connecting a plurality of different types of rock materials or ground materials 22A to 22D whose internal elastic wave velocities are known, receiving the direct wave and the reflected wave of the generated elastic wave by a sensor 16, and verifying elastic wave propagation characteristics based on received waveform data.SELECTED DRAWING: Figure 1
【課題】反射波の極性反転と岩盤性状の関係を容易に精度高く繰返し検証することができる弾性波伝搬特性の検証方法および検証装置を提供する。【解決手段】岩盤または地盤の弾性波伝搬特性を検証するための方法であって、内部における弾性波速度がそれぞれ既知である複数の異なる種類の岩盤材料または地盤材料２２Ａ〜２２Ｄを繋ぎ合わせてなる試験体１２の内部に弾性波を発生させるステップと、発生した弾性波の直接波と反射波をセンサー１６で受振するステップと、受振した波形データに基づいて、弾性波伝搬特性を検証するステップとを備えるようにする。【選択図】図１
