摘要
简述了震电效应及利用震电效应超前探测含水体的理论基础。在放炮掘进的隧道内,通过观测放炮前后震电信号的强弱变化可以探测周围含水地质体。初步现场试验表明,震电法探测距离远,探测准确性随掘进面推进可循验证,是一种可行的极具潜力的隧道含水体超前探测预报方法。
The theory basis of electric shock response and advanced water exploring with electric shock method are introduced.Observing the variation of signal degree before and after blasting in the tunnel can explore the surrounding water-carrying geological-body.The preliminary on site test shows that the distance and accuracy of electric shock method can be verified with push of the tunneling and a feasible potential method to advanced explore the tunnel water-carrying geological-body in tunnels.
