Analysis of the Influence of Different Gas Collecting Devices on the Quality of Fault Gas Observation Data
In this paper,we analyzed the influence of heavy rainfall on the observation data of fault soil gas in the Suqian section of the Tanlu Fault Zone.We obtained some practical design and construction schemes of fault soil gas observation gas collecting pit in arid areas in the middle and west of our country.The influence of environmental factors,such as shallow groundwater depth,abundant reserves,and frequent seasonal heavy rainfall,cannot be effectively excluded in the southeast of China.Moreover,the strong rainfall in summer could cause the rapid rise of the diving surfaces and the failure of the Scintillation Chamber,which further causes the rapid decrease of the radon concentration and interferes the analysis of the earthquake precursor.Therefore,the researchers should take into account that the instrument parameters and operating environment should be adapted to the local conditions to improve gas gathering facilities and observation well equipment,which is helpful to meet the technical requirements of fault soil gas observation in the southeast China.
