Analysis on the factors affecting dynamic variation of positive and negative barometric coefficient of well water level
摘要
Abstract
According to the different types (explicit type, implicit type and middle type) of dynamic change of well water level under the action of the air pressure, the barometric coefficient of well water level is obtained by use of linear regression method. The analysis results show that the barometric coefifcient, positive and negative changes are relevant to non-tectonic stress and tectonic stress factors that caused the change of well water level etc. In the actual tracking analysis of barometric coefficient dynamic change process, absolute value of barometric coefficient is indispensable. When the barometric coefifcient absolute value is too large or too small, ifrst of all to exclude well water level is affected by non tectonic stress factors. If after excluding barometric coefifcient absolute value is too large or too small all the same, which may be related to tectonic stress change, this is our most concern. Some high value and negative anomaly of the barometric coefifcients is identiifed by some authors as the seismic anomaly that is not precise.关键词
