利用同一地质单元内的水震波与地震面波资料进行对比研究，估算水位对含水层应力应变的响应“格值”。选取唐山矿井水震波资料、唐山陡河地震台记录的地震面波资料，估算“格值”是9.182×10－10／cm，即唐山矿井观测含水层垂直应变量为9．182×10-10／cm，时，井水位变化1cm。
Using the data of seismic waves and seismic waves in the same geological unit, the “grid values” of water level response to stress and strain of aquifers are estimated. The data of Tangshan mine water shock wave and the seismic surface wave recorded by Tanghe Seismic Station are used to estimate the “grid value” of 9.182 × 10-10 / cm, that is, the vertical strain of the observed aquifer in Tangshan Mine is 9.182 × 10-10 / Cm, when the well level changes 1cm.
