【摘要】 利用地下氡气、浅层地震和高密度电法三种方法在探测隐伏断层方面开展了对比研究,并结合地质工作现场验证,表明地下氡气测量异常值可判定隐伏断层初步位置;利用地下氡测量方法对另两条断层进行了地质走向判定,克服了其他物探方法费时、成本高等难题。在实际工作中地下氡测量将为其他物探方法、工程实施等提供借鉴参考。更多还原

【Abstract】 In this paper,underground radon gas measurement was used in the work to find concealed unusual polarization characteristic faults.The authors employed shallow seismic exploration technology and high-density electrical method to give comparative validation in combination with geological in-situ verification.Analysis shows that the abnormal values obtained from radon measurement can well indicate locations of faults.With the underground radon measurement method,the authors detected the alignment of two other faults in the earthquake area,and made an evaluation of their relative activities.This method overcomes the time-consuming and high cost problem existent in other geophysical methods.In practical work,underground radon measurement provides the reference information for conducting other geophysical methods and implementing projects.更多还原
