摘要
断裂构造的勘察和评价是岩土工程的重要工作之一。断层气体地球化学方法可以用于断裂构造的勘察和评价 ,主要用于 :确定断层的位置、规模和产状 ;定性分析断层的活动性 ;研究断层的切割深度或断层性质 ;场地地震危险性评价、地震烈度的标定和地震区划。
The survey and evaluation of fault and its activity is an important part of geotechnical engineering investigation.Gas geochemistry method can be used in the fault investigaton.Study on fault gases could help us to locate the faults,especially for the buried fault,to determine the fault's scale,attitude,cut depth,and to analyze the activity of fault.Meanwhile,time?spatial variation fault gas field could provide a great amount of additional imfomation for site sesmic risk analysis,calibrition of seismic intensity and seismic microzoning.
