摘要
通过对南京某深基坑降水设计与降水效果分析表明 ,该基坑采用大降水与回灌相结合的降水方案是可行的 ;利用裘布衣公式、大井法试算、干扰井群叠加原理相结合的设计方法保证了降水过程实施的可行性 ;及时利用降水过程中水位观测资料绘制等水位线图 。
Based on a deep foundation pit in Nanjing, the groundwater lowering design and the effectivity analysis indicate that adopting large groundwater lowering and artificial recharge is reasonable. By using integrated Dupuit formula and large-well method and disturbed multiple well system, feasible lowering operational process of the deep foundation pit has been guaranteed.In the lowering process, periodic isoline maps according to water level observation data play an important role in dynamic design.
