场地地震安全性评价中的近场区活动断裂评价是确定近场区地震活动水平的重要一环。实践证明，地球化学方法探测隐伏活动断裂效果很好．本文利用地球化学方法确定了瘦狗岭断裂东段的具体位置．
The assessment of near-field zone active faults in site seismic safety assessment is an important part of determining the seismic activity in the near-field zone. Practice has proved that geochemical methods to detect hidden active fault effect is very good. In this paper, the geochemical method was used to determine the specific location of the eastern section of the Zhanggulingling Fault.
