Abstract: Based on the large well method, through the in-depth study of the influence mechanism of the suspended water stop curtain, combined with the groundwater seepage theory, the theoretical calculation formula of the foundation pit water inflow under the condition of suspended dewatering was derived. Through the numerical calculation of the engineering example, this method had high precision, and the suspended dewatering condition was efficiently and accurately estimated with the limited known conditions in the early stage of the foundation pit, therefore the current foundation pit dewatering design theory could be improved and perfected.
