| 摘 要： | 为了给城市工程建设规划提供基础地质资料,需查明区内断裂的准确位置、产状以及覆盖层厚度。利用反射波法地震勘探、瞬变电磁法、可控源音频大地电磁法进行勘察工作。虽然区内人文干扰和电磁干扰严重,但是野外施工时采用了多种手段以保证观测数据的可信度,三种物探方法的数据采用不同的方式进行处理,分析反演结果并结合已知地质资料,给出了区内断裂的准确位置等信息。进行隐伏断裂勘察时不能只采用单一的物探方法,必须采用综合物探的方法,才能准确地反映出隐伏断裂的位置、产状等信息。

| Abstract: | In order to provide basic geological information for a urban construction plan,it is necessary to identify the precise location of the faults,the occurrence and the thickness.In this paper,we used seismic reflection method,transient electromagnetic method and controlled source audio-frequency magnetotelluric method to do the exploring work.As there was strong electromagnetic interference in the exploring area,we took many measures to ensure the data obtained credible.Therefore,the data from three kinds of g... |
