| 摘 要： | 在西宁市城市活断层探测工作中利用FD-3017RaA测氡仪开展了隐伏断层土壤气氡的探测，探讨了断层的气体地球化学特征及其确定隐伏断层的方法。在进行的8条测线上进行了土壤气氡的野外现场测量，共1384个点。结果表明，在8个地球化学剖面中确定了2处异常，由此确定了断层的大体位置，该处的人工浅层地震勘探结果也证实断层的存在和具体位置。土壤气氡测量法作为辅助探测手段在大城市活断层的探测工作中有一定的参考意义。

| Abstract: | The soil radon is tested in potential faults by FD - 3017RaA instrument in urban active faults exploration in Xining, and the geochemical characteristics and the methods of potential fault determination are discussed. The results show that 2 points are determined to be abnormal in 8 geochemical profiles, and the fault position is determined according to the results and the artificial shallow earthquake prospecting results. The soil radon test as a supplementary method is helpful in urban active faults exploration. |
