| 摘 要： | 本文利用土壤气氡方法对邢台地区5条隐伏断裂的重点地段进行了12个剖面的定位探测。结果发现,断裂带中地球脱气现象十分强烈,而远离断裂地球脱气则迅速减弱。在12个测量剖面中,A级异常点(段)有9个。经过数据处理和对比分析,在排除可能的干扰因素的基础上,应用气氡异常给出了5条目标隐伏断裂在地面延伸的较精确的位置。

| Abstract: | In order to locate five concealed faults in Xingtai City, 12 profiles of soil gas (Rn) survey were set up crossed the faults. It is found that on above the faults strong degas is detected, but in two sides far away from the faults degas is very weak. Of 12 profiles, 9 show the gas radon with obvious anoma1ies in the soil on faults. Through data processing and comparative analysis, we rule out the possibility of interference factors, and determine the extending location of five buried faults on the ground su... |
