| 摘 要： | 利用测量土壤中氡气异常来确定隐伏断裂的几何学特征。在缅甸拉泰—其培河段布置的四条测氡剖面中,氡气异常明显,拉泰-芒童段异常值约为本底值的3～8倍,芒童以南部分异常值比本底值高100倍,表明芒童以南地段活动性较强。氡气测量结果很好地控制了恩梅开江断裂在覆盖层之下的延伸展布方向。地表开挖及平硐揭露,很好地验证了测氡结果所推测的断层几何学特征。因此,测定土壤中氡气异常来寻找隐伏断裂的方法是可行的。

| Abstract: | Geometrical characteristics of hidden faults can be determined by measuring the radon anomalies of soil gas.Among four sections in the project of the Chipwi hydropower station of Myanmar,the abnormal soil radon gas is evident.The abnormal radon value near the dam area is about 3 to 8 times the background value,and the radon value of the southern dam is 100 times the background value,showing that the activity near the southern dam area is stronger.The under-coverage trend of the Nmai Hka fault is... |
