摘要
国内外大量地震震例研究表明,巨大的城市地震灾害主要是由隐伏于城市地域之下的活动断裂上发生的地震造成的,因此,探测城市地域内的活断层是十分必要和紧迫的一项工作。浅层人工地震是一种分辨率高、探测结果可靠的断层探测方法。通过试验,确定了用浅层人工地震探测长春市地域内断层的探测方法和采集参数等。在长春市的断层探测中,大量采用了浅层人工地震方法,并取得了较好的效果。
Research on a large number of seismic events at home and abroad has indicated that tremendous earthquake hazards in urban areas are mostly attributed to earthquakes caused by active faults buried beneath the cities. Shallow artificial seismic exploration is a feasible method for fault exploration, which has high resolution power. Exploration method and collection parameter of shallow seismic exploration was acquired by test. Shallow artificial seismic exploration is applied largely to exploration of fault in Changchun. The exploration result is availability.
