| 摘 要： | 通过砂土一维循环压缩试验，模拟了地下水位升降引起的含水层的压缩和回弹变形，分析了砂土竖向变形、孔隙率随循环次数的变化规律，提出了用孔隙降低率评价地下水位升降对地下水库库容影响的方法，得出地下水位的反复升降一般不会影响地下水库正常使用的结论。

| Abstract: | Through doing one-dimensional equal amplitude circulating compression test of sand,the compression and resilience deformations of the aquifer caused by the groundwater level rising or falling are simulated;and the effect of the circulating number on the vertical deformation and porosity is analyzed;the reduction rate of porosity is proposed;the influence of groundwater level rising or falling upon the groundwater reservoir storage is evaluated by the reduction rate of porosity;a conclusion is obtained that rising or falling of groundwater level will can not affect using of groundwater reservoir. |

| Keywords: | circulating compression test porosity groundwater reservoir fall ratio of porosity |
