摘要

2001～2003年为奥运工程规划、建设开展了对北京奥林匹克公园区域中黄庄—高丽营断裂的探测,本项工作另一探索性任务是为随后即将在全国开展的城市地区隐伏断裂探测工作摸索有效方法、积累经验.本次探测先采用电阻率层析成像和浅层地震勘探方法进行断裂定位,再钻探进行断裂准确定位并探测断裂结构和地层结构,结合对所采集样品进行的~(14)C、红外释光、古地磁、孢粉等多种测年方法进行地层年代划分.通过多种方法并行对比、验证、综合分析,以多方面综合性大量研究工作明确给出了断裂位置、结构、活动性,认为本段断裂最新活动时代为早更新世(非地震活断层).根据实践经验探讨了城市地区隐伏断裂探测的有效方法.
The Huangzhuang-Gaoliying fault in Olympic Park area is explored for Beijing Olympic project.First,electrical resistivity tomography and shallow seismic exploration were used to locate the faults,further,drilling for the precise position and structures of the faults and the stratigraphic configurations was carried out.On the basis of the radiocarbon age,OSL,paleomagnetism and pollen dating,the formation ages are divided.Lastly,the location,structure and activity of the fault are clearly provided.The latest activity of the fault in the area happened in Early Pleistocene so the fault in the area is not seismic active fault.The work is meaningful for searching effective methods and accmulating experiences for prospecting buried faults in urban-area.
