【摘要】 近年来在公路隧道的勘探中,越来越重视物探的应用。本文从介绍瞬变电磁法的探测原理入手,介绍了在祝源隧道勘察过程中,应用瞬变电磁法进行勘探的情况。瞬变电磁法的勘探结果较好地揭示了隧道区间断层分布及在深部延伸状况,经过钻探及地表调查验证,效果良好,解决了工程中存在的实际问题。更多还原

【Abstract】 In recent years,applications of geoexploration in the deep and long tunnel prospecting is paid much attention to.In this paper,starting with presentation of TEM’s theory,the application of TEM is introduced in the Zhuyuan tunnel engineering geological exploration.The result of TEM exploration shows the condition of distribution and deep extension of the fault in the tunnel area.And also the result was validated in the later drilling exploration,and the problem of the tunnel was solved.更多还原
