地球物理方法对城市活断层的探测与研究
|
摘要
采用综合地球物理方法对长春市活断层进行探测,实践证明,利用联合剖面法、高密度电法、地质雷达、瞬变电磁法、高分辨率地震和重磁方法等,在研究活断层的位置、产状与形态上均具有很好的作用,针对城区干扰因素多环境复杂等不利因素,通过采用新的数据处理方法技术,取得了理想的探测效果,为今后开展活断层的探测与研究提供了借鉴.
We use the comprehensive geophysics methods in changchun city active fault detection,practice proves,using the geophysics methods such as AMN-MNB measurement,resistivity imaging,Ground penetrating Radar(GPR),high resolution seismic reflection,transient electromagnetic(TEM)method,gravity and magnetic survey etc study of position and form of active fault,The good effects have been gotten on active fault.In view of disadvantages such as many interfering factors and complex environments in city,using new methods and technology,data processing and explanation,and using the characteristics of different methods,we has obtained the ideal survey effect,which can be used for reference in active fault detection in china.
