| Abstract: | The causes and regular pattern of earth layer compression and land subsidence caused by overpumping groundwater at depth in north-China plain are analysed.According to the nonequilibrium flow pumping principle of groundwater at depth and the theory of stratigraphic seepage consolidation,the amounts of deep clay layer compression and land subsidence caused by ground water level recession are calculated. |

| Keywords: | aquifer ground water level groundwater drawdown funnel additional effective stress earth layer compression land subsidence |
