【摘要】 从活动断裂的研究和进展出发,通过追溯国内外活动断裂研究发展历史,结合国际当前活动断裂研究的方法与趋势,认为地球物理方法是城市活断层探测的重要方法之一。文中重点介绍了在城市地震活断层探测中用到的地球物理方法的类型和主要特点,特别是在区域探查与初步鉴定阶段、详细探测与精确定位阶段、孕震构造探测阶段可能涉及到的各种地球物理探测方法、适用范围及所能解决的主要问题。同时,结合哈尔滨城市活断层探测项目实例,证明地球物理方法在城市活断层探测工作中甚为有效。更多还原

【Abstract】 Reviewing the research of the active faults at home and abroad and combining the method of the present research on the active fault abroad,the paper proposes that the geophysical method is one of the most important methods.In this paper,it introduces various kinds of possible geophysical methods for seismic active fault exploration and their main features.It also discusses the scope of application of related geophysical methods and the major problems that they can solve in the different periods of active fault exploration,such as regional survey or preliminary investigation,detailed exploration or precise location and so on.Meanwhile,the discussion proves that the geophysical method has a good effect on urban active fault detection through the example of active fault detection in Harbin city.更多还原
