Abstract

To analyze the factors affecting the water inflow of suspended water stop curtain foundation pits and study the water inflow patterns caused by the pressure reduction and precipitation process of pressurized water under different conditions, this paper adopts finite element numerical analysis method. Taking a suspended water stop curtain foundation pit project under construction in the water rich strata area of the Yangtze River floodplain as an example, by controlling a single variable, the factors that cause the water inflow of suspended water stop curtain foundation pits under the condition of containing pressurized water are analyzed one by one. The variation law of unit flow rate at half width of foundation pit with curtain distance under a single influencing factor is given. The results show that the inflow of confined water is directly proportional to the permeability coefficient, and both decrease with the increase of the depth of the water stop curtain; The water inflow increases with the increase of the water level drop in the foundation pit, decreases with the increase of the influence radius and increases with the increase of the excavation depth of the foundation pit; As the distance from the curtain increases, the amplitude of unit flow change gradually decreases; There is an optimal insertion depth.
