Embodiment 1
[0089] like figure 1 Shown is the three-dimensional numerical model of the seepage in the foundation pit water level pumping process established on the remote server by using the seepage three-dimensional finite element analysis software, and the model is meshed, and the initial condition of the groundwater surface within the analysis range is set to be horizontal. Assign material parameter values, the rectangular structure in the figure is the foundation pit, and the circular structure is the water level pipe.
[0090] figure 2 Yes figure 1 The plane schematic diagram of the three-dimensional numerical model in , in which the pumping of the C1 water level hole is taken as an example to carry out numerical simulation. In the simulation analysis process, the value range of the permeability coefficient K is from 0 to 10 (unit: 10 -10 m 2 / p a / sec), so it is divided into 5 equal parts, that is, in the analysis software, the permeability coefficient K of the model is assign...
