| 摘 要： | 本文论述了西安地裂缝0.5m和2.0m深处CO_2异常特征,并对其异常机理进行了初步探讨。结果表明,0.5m深处CO_2异常范围较大,与地裂缝造成的破坏范围基本一致,其CO_2主要来源于生物作用;2.0m深处CO_2异常范围窄,与主地裂缝的位置有很好的对应关系,其CO_2主要来源于断裂活动造成的碳酸盐岩破裂释气。

| Abstract: | This paper discusses the characteristics and mechanism of anomalies of CO_2 concentrations in 0.5m and 2.0m depth of the ground fissure in Xi'an. The results indicate the anomalous ranges of CO_2 concentrations in 0.5m depth are wide and approximately equal to the ranges damaged by the ground fissures. CO_2 from 0.5m depth is mainly originated from, biogenic agency. But the anomalous ranges of CO_2 concentrations in 2.0m depth are narrow and closely relative to the locatigris of the main ground fissures. CO_2 from 2.0m depth is mainly originated from rupture, of carbonate rock caused by fault movement. |
