摘要
通过对天津市滨海新区不同埋藏深度内弱透水层水理性质变化的研究,得出不同埋深弱透水层的孔隙水类型,依据其不同的孔隙水类型揭示出不同埋深弱透水层的释水变形机理．提出了以界限含水量为依据,对不同埋深弱透水层采取不同的变形计算模式．
The water physical properties of aquitard at different depths were studied with the aquitard of Tianjin City in China as an example. The results showed the pore water styles of aquitard at different depths and the corresponding deformation mechanisms. For different deformation mechanisms of aquitard, this paper advises using different calculating models to calculate the deformation of aquitard at different depths according to the moisture content of aquitard.
