山地地盤の研究(I) ―弾性波探査による田上山地の花崗岩風化帯について―

Abstract

The methods of seismic prospecting using P-waves were investigated on the ground of weather-ed granite zone at mountainous region. Its object were that to made clear for mecanism of weath-ering on the ground at mountainous region. At the ground of weathered granite zone, it was madeup o! become three type structures with VI, VII and VIII.Specially, on the layer pointed out VII, it was concerned for the poporse of weathering relativeto granite rocks. It obtained the response that be possible show the exponetial curve from Vp in VII.
