摘要
对于深埋洞库,尤其是有较厚覆盖层情况下,一般的物探手段难以测到洞底标高,利用EH4可以弥补一般物探手段测深不足的缺点,较准确地探测1-2km深度范围内岩土体的视电阻率,判定围岩级别、富水带、断层破碎带、岩性、岩体完整性、测定覆盖层厚度等,有效解决深埋洞库的勘察问题。
For deep buried hole library,especially more thick cover layer situation,General geophysical means difficult to measuring to hole the end of elevation,use eh4 can make up for general geophysical means measuring deep less than shortcomings,more accurate Detection l-2km depth range in the rock soil body depending on the resistance rate,determine surrounding rock level,and rich water with,and fault broken with,and rock sexual,and rock body integrity,and determination of cover layer thickness such as,effective resolve deep buried hole library investigation problem.
