摘要
在铁路建设中,对长大深埋隧道的勘察,需要对各种不同深度的地质体进行探测,采用磁源瞬变电磁法工作前必须通过实地试验工作,合理地选取工作装置、设置仪器参数。从方法原理特点出发,结合实例总结出了一组适合瞬变电磁仪进行浅、深部探测的工作参数及需注意的问题,实践表明磁源瞬变电磁法在铁路隧道勘察中具有很大的应用潜力。
From the method principle of the transient electromagnetic method, combining function of the equipments, the paper describes the fieldwork method and technique,the method of data explain and the main regulation of magnetism source transient electromagnetic method to the railway tunnel exploration. The paper recounts relationship between the choice of operating parameters and the exploration depth. In final the article explains the good result from two successful examples of magnetism source transient electromagnetic method to the railway tunnel exploration.
