| 摘 要： | 利用断层土壤气探测方法，在珊溪水库地区双溪-焦溪垟断裂上3个不同位置进行土壤Rn和H2的测量，发现断裂带上的土壤Rn和H2测值在靠近断层破碎带或岩脉出露位置明显升高。结合断层气探测方法在探测隐伏断裂方面的应用，确定双溪-焦溪垟断裂在包山垟村附近具体经过位置。发震断裂上的土壤Rn和H2测值明显高于非发震断裂，说明珊溪水库地区土壤Rn和H2与地震活动性关系密切。

| Abstract: | Based on measurement, obtained through the soil gas detection method, of the radon and hydrogen in soil gas on 3 different positions of Shuangxi-Jiaoxiyang fault in Shanxi reservoir district, we find that the values of radon and hydrogen in soil are higher near the fault fracture zones or veins, and the values of radon and hydrogen in soil far away from the fault fracture zones are lower. By the application of fault gas detection method in detecting buried faults, the fault crossing location near Baoshanyang village can be confirmed. We also find that the values of radon and hydrogen in soil gas crossing the seismogenic fault are significantly higher than the values crossing the non-causative fault. This shows that the radon and hydrogen in soil gas are closely related to seismicity, so continuous measurements of soil gas near the Shuangxi-Jiaoxiyang fault are suggested to provide the basis for seismic forecast and shock tendency estimation in Shanxi reservoir district. |
