摘　　要：隐伏断层的勘探是各种工程施工的一项重要任务。在分析隐伏断层地表氡值形成规律的基础上,结合研究区测氡法观测数据的分形分析和异常解释,划分氡值异常范围,并解释地下断层信息。研究发现:分形方法相对于统计学方法可以合理地划分异常范围;通过地表氡值的峰形可以初步判断地下隐伏断层的倾向。The detection of blind fault is important in various engineering construction. Based on the analysis of ground radon value formed in blind faults, we detect the blind fault in research area by using radon measurement, to calculate the anomaly threshold of radon value, divide the radon anomalies and explain the information of underground fault, both fractal theory and statistical method were used. The study found that fractal theory is more reasonable than statistical method in dividing the abnormal range; the tendency of blind fault can be initially estimated by the radon leptokurtosis near the surface.
