- Abstract:
- The groundwater is an important factor for the safety of foundation pit, In order to analyse the distri-.bution of seepage field under different calculating conditions with seepage control measures, a typical canalstretch was modeled for construction period of Middle Route Project of $NWT, The numerical simulation re.sults show that the pit safety would decrease with the less permeable layer being excavated step by step and aquifer confined beneath it , so measures should be taken to control and regulate the seepage field. The efficiencyof foundation pit dewatering would be affected by the water recharge boundary, the thickness and permeabilityof the aquifer , the arrangement of dewatering wells, and so on.
