城市地震活断层探测的地球物理方法

通过国内外有关城市地震活断层探测的实例，对城市地震活断层探测的主要地球物理方法进行了介绍。由于城市地区特殊的干扰环境，城市地震活断层探测需要对传统的技术方法进行必要的改进和调整。以提高探测方法的抗干扰能力，城市地球地震活断层探测应充分利用高分辨浅层地震勘探和人工地震测深精度高的优势，根据不同城市的地球物理特征，配合电法勘探、磁法勘探、重力勘探和天然地震观测等其他地球物理方法，通过对资料的综合分析和解释，提高探测结果的分辨率和可靠性。

Geophysical Methods of Seismically Active Fault Detection in Cities

This paper introduces the main geophysical methods of seismically active fault detection in city areas,through some examples about seismically active fault detections in some cities at home and abroad. Because of specific interference environment of city areas,it is necessary to improve and readjust traditional technical methods in seismically active fault detections of city areas,so as to increase the anti interference ability of the detection methods.The seismically active fault detections in cities should make full use of high resolution shallow seismic prospecting and sounding of artificial earthquakes,which has the advantage of high precision,according to the geophysical features of various cities,coordinating with other geophysical methods,such as electrical prospecting,magnetic prospecting,gravity survey and natural earthquake observation,through a comprehensive analysis and interpretation to increase the resolution and reliability of detection results.
