| Abstract: | The two key problems to be solved for deep founation pit dewatering in fine grained confined aquifer are: to guarantee the quality of the forming of dewatering well, the effect of dewatering can be ensured; second, the pumpingg test data must be obained accurately, then using the pumping test data to calculate the water dischargr of foundation pit, so as to select the dewatering facilities and ascertain the umber of dewatering wells and its layout. |

| Keywords: | confined aqifer quality of well forming water discharge |
