摘要
介绍了一种利用日本产的ＤＳＳ５０２０Ａ型双通道记忆示波器测量表层和底层岩体波速及表层厚度的“一击双收”检测方法，它特别适用于不能造孔的岩体、软弱岩体、不均匀介质的波速测量。给出了所依据的原理。
A quick,convenient and reliable detecting technique called “one percussion ,two receptions”,which means:when a percussive force acts on rockmass by one time,two transduces receive signals of shock wave simultaneously ,is represented.The detecting technique is used to measure the wave speeds of the surface layer and bottom layer of rock masses and then the thicknesses of the surface layer, by a two tunnel memory oscillograph titled DSS5020A made in Japan.It's especially suitable for measuring wave speed of soft rock mass,unhomogeneous medium and the rock mass on which a hole is unable to be bored.Its basic theory,operation method and application examples are also expounded.
