| 摘 要： | 利用气体地球化学方法对乌鲁木齐市城区７条隐伏断裂的重点地段进行了１１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，而远离断裂脱气则迅速减弱。１１个剖面中９个剖面的土壤气氡在断裂上方异常显著，６个剖面的土壤气汞对断裂反映明显。经过数据数据处理和对比分析，有６条隐伏断裂在地面延伸的位置得到了较精确的判定。应当指出，地下水和人为开挖等因素对城市隐伏断裂的气体地球化学探测有较明显的干扰。

| Abstract: | In order to locate seven concealed faults in the city proper of Urumqi, 11 profiles wereset on the focal segments of the faults,and the gases (Rn,Hg)in fault soil were surveyed. Itis found that in the faults,the gas seperation of earth is strong,but in two sides far awayfrom the faults it's rapidly weakened. Of 11 profiles, 9 show the gas radon has clear anomalies in the soil on faults and 6 show the gas mercury has the same reflection of faults- By dataprocessing and comparative analysis,6 of 7 concealed faults have been determined more accurately. It should be pointed that ground water, engineering excavation,etc., interfere withthe gas geochemical survey of urban concealed fault obviously. |
