断层带土壤气逸出浓度影响因素及台阵映震能力研究
Influencing Factors of Soil Gas Emission Concentration in Fault Zone and Seismic Reflection Ability of Seismic Array
摘要
Abstract
Based on the data from 10 stations of the Suqian Seismic Array for fault soil gas observation in the past three years,this paper analyzed the characteristics of radon,hydrogen,and carbon dioxide emission concentra-tions and studied the relationship between the emission concentration of different types of soil gases and faults in dif-ferent geological periods.Moreover,the extent to which the annual variation of the data was influenced by tempera-ture,air pressure,and rainfall was explored.Combined with the ML3.7 earthquake in Sihong,the radon data in soil gases showed the phenomenon of synchronous trend change,and the seismic reflection ability of the seismic ar-ray was analyzed.The results show that the dynamic changes of radon,hydrogen,and carbon dioxide concentra-tions in soil gas are closely related to climatic factors.Radon observations are affected by rainfall and the carrier gas role of carbon dioxide.The synchronous trend changes in the array data have indicative significance for the detec-tion of pre-earthquake anomalies.关键词
