THE COMPARISON OF THE THREE METHODS OF INVERSION OF STRSS CHANGES OF AQUIFERS USING STEP CHANGES OF WELL LEVEL

Zhang zhaodong , Zheng Jinhan , Feng Chugang , Zhang Guangcheng Abstract: This paper sums up three methods of inversion of stress changes of aquifers using theoretical results, the effect of well barometric pressures and the effect of the earth tide responses and presents respectively die quantitative relationship between the step changes of the three types of well water tables and the stress on the aquifers.The paper also discusses the feasibility and advantages and disadvantages of these three methods.
