| Abstract: | Based on draw down project for deep excavation of a subway station in loess region,engineering geology conditions, hydro geological conditions and field pumping test are employed to study the influence radius of foundation pit dewatering and field comprehensive permeability coefficient. Based on this, calculation and design for precipitation of deep foundation pit are done. The paper sums up the general technological process of dewatering and some problems that should pay attention to in precipitation process. Relevant methods and design can provide a reference for similar projects. |
