地震反射法勘探在广州市三元里地区的应用效果
|
摘要
本文介绍了在广州市三元里地区的地质条件下,应用地质雷达、反射法地震勘探和井中电磁波透视探测岩溶的对比情况。文中叙述了横波反射法在三元里地区应用受限的原因及纵波反射法在本地区为压制干扰、提高分辨率所采取的措施,使P波反射法勘探取得了好的效果。文中给出了该区P波反射法探测基岩界面、溶洞、断层和溶蚀带分布的应用实例。
Under the geological conditions of Sanyuanli District of Guangzhou City , this paper introduces the comparative circumstances of the application of georadar , seismic reflection exploration and the downhole electromagnetic wave perspective investigation of karst . In the paper , it narrates the cause of limitation of the application of transverse wave reflection method and the measures taken for the longitudinal wave reflection method in this district to suppress the interference and enhance the resolution and good results are obtained . A case history of the application of the P-wave reflection method in that area to investigate the bedding plane of bedrock, karst cave , fault and the distribution of the dissolution belt is given.
