本文将加卸载响应比的理论和方法引入到地下水位潮汐资料计算中来， 从岩石的应变与应力的非线性响应分析了井水位固体潮加卸载响应比的物理机理， 从理论上论证可以应用地下水位观测资料来计算加卸载响应比， 并研究出利用地下水位对固体潮响应来计算加卸载响应比的方法。以此方法计算了我国大华北地区部分井水位的固体潮加卸载响应比， 分析了唐山１９９１ 年５１ 级和１９９５ 年５０ 级地震前后地下水位固体潮加卸载响应比的变化特征。
In this paper, the theory and method of loading-unloading response ratio are introduced into the calculation of tide data of groundwater level. The physical mechanism of well-unloading-response ratio of well water tide is analyzed from the nonlinear response of rock strain and stress. Groundwater level observation data to calculate the unloading response ratio, and to study the use of groundwater level on the solid tidal response to calculate the unloading response ratio method. Based on this method, the response ratio of solid tide to unloading response of some wells in the northern part of North China was calculated and the variation characteristics of the unloading response ratio of groundwater tide between tidal flat and groundwater level before and after the May 1991 1991 and May 05 1995 earthquakes were analyzed.
