摘要
在岱海断陷带2条活动断裂上布设了4个用于观测土壤H_(2)的剖面。在2017年5月底测量土壤H_(2)浓度,布设测线8条,测点共122个。测量结果表明,岱海断陷带2条活动断裂上土壤H_(2)的浓度在断裂两侧明显高于断裂河沟谷底测点。
H_(2) in soil gas was measured at one hundred and twenty-two sites in the two faults around Daihai graben,in May 2017.The results indicated that the H_(2) concentrations in the soil gas from the two faults are significantly higher in Daihai graben than those on both sides of the faults.In a word,analyzing the relationship between fault activity and H_(2) in soil gas in Daihai graben can greatly increase the capability of seismic monitoring.
