潍坊市主要隐伏断层活动特征研究
Study on Blind Faults in Weifang Urban Area
【摘要】 利用浅层人工地震、电法勘探和工程钻探等多种方法在潍坊市开展了隐伏活断层探测工作,查明了潍坊市城区周围沂水-汤头断裂、鄌郚-葛沟断裂、寒亭断裂和潍县断裂等6条主要断裂的位置;通过释光(TL、OSL)和电子自旋测年(ESR)研究了这些断裂的最新活动时代。结果表明,潍坊市城区范围内无活动断层通过,为土地利用和城市建设规划提供了科学依据。
【Abstract】 Active faults in Weifang city and surrounding areas are studied with geophysical surveys such as shallow artificial seismic prospecting, electrical exploration and combined with engineering drilling. Six main faults are detected including Yishui-Tangtou fault, Tangwu-Gegou fault, Hanting fault and Weixian fault, etc. The latest active age is determined by OSL, TL and ESR dating techniques. No active fault has been found so far in Weifang urban area. Our results provide a scientific basis for land utilization and city planning.
