| 摘 要： | 在隧道施工过程中经常会遇到含水的破碎带,如果不能提前采取处理措施,将会引起突水、塌方等地质灾害,严重威胁施工安全.由于含水破碎带通常表现为地震波速降低,瑞雷波发生速度频率分散;而对于电法勘探则表现为低电阻率.本文提出了应用瑞雷波和瞬变电磁法相结合的综合探测方法,即综合分析低波速、低电阻率的"双低"区,能够较为准确的确定...

| Abstract: | In the tunnel construction the water-bearing fracture zones are often encountered in,if the advance treatment isn't taken,it would give rise to the water gushing,landslides and other geological disasters,which seriously threat the construction safety.The seismic wave velocity in water-bearing fracture zones usually presents the lower rate,and the dispersion of the velocity frequency of Rayleigh wave occurs.When the electrical prospecting is used,the low resistivity occurs.The comprehensive application of Ra... |
