| 中文摘要: |
| 为加快铁路工程建设,提高勘察效率,对铁路隧道洞身必须开展水文地质调查和地球物理勘查,运用音频大地电磁方法(AMT)是深埋隧道勘察的一种非常有效、高效的方法,为工程地质问题提供基础性资料,并且可以很好地指导钻探工作的布置,以某隧道音频大地电磁勘查为例,分别对音频大地电磁法的原理,采集、处理等问题进行分析介绍,针对复杂地形的数据采集进行优化处理,并结合实际地质资料对该隧道的地层分布、断层及其破碎带的富水情况等进行分析和解释,并取得了理想的效果。 |
| 英文摘要: |
| In order to speed up railway engineering construction and improve exploration efficiency,hydrogeology survey and geopysical exploration must be carried out for railway tunnel trunk.Audio magnetotelluric method(AMT) is a very effective and effcient method for deep-buried tunnel exploration,which provides basic information for engineering geological,and can well guide the layout of drilling work. Audio magetotelluric prospecting is taken as an example.The principle,acquisiton and processing of AMT method are analyzed and introduced respectively.The data acquisition of complex terrain is optimized.The stratum distribution of surrounding rock,water-rich situation of faults and fractured zones of the tunnel are analyzed and explained with practical data,and ideal results are obtained in its applicaiton. |
