摘要
京北地区有3条活动断裂,即指黄庄-高丽营断裂(代号定为HG)、南口-孙河断裂(代号定为NS)和夏垫断裂(代号定为XD)。地球化学探查与观测,较地球物理探查与观测,具有技术简单、解释直观,效果明显等优点,因此在地震工程与监测中得到广泛的应用。本文在收集、归纳,整理已有成果的基础上,请原测人员到现场核实后,补测了测线方位及测线起止点与地球化学观测点的坐标,使京北地区活动断裂有了精确的定位,为将来城市建设避开活动断裂的干扰,提供了地质技术支持。
There are 3 active faults in North Beijing, which are named Huangzhuang-Gaoliying fault （ab. HG）, Nankou-Sunhe fault （NS） and Xiadian fault （XI））. Comparing to geophysics, the geochemical exploration and observation has the characteristics of easy operation, intuitional interpretation and obvious showing result. So it is widely used in earthquake engineering and monitoring. Based on data collection and local verify of original investigators, we surveyed coordinates of geodesic azimuth, point of begin-end and observation station of geochemistry, to confirm location of active faults. It provided geological technical support for city constructions to keep away from disturbs of active faults.
