In order to better utilize the groundwater seepage field under artificial conditions as a technical tool, it is necessary to study the infiltration properties of soil, the infiltration law of groundwater in the soil layer and its relationship with engineering. Therefore, this paper takes the HM area as the study area according to its hydrogeological characteristics, and divides the aquifers into submersible aquifers as well as the Ⅰ, Ⅱ, and Ⅲ pressurized aquifers in order from top to bottom. The hydrogeological conceptual model was established, and the soil deformation direction was analyzed according to the Terzaghi effective stress principle to form a coupled groundwater flow-soil deformation model. On the basis of the finite element discretization method, the finite element governing equations of the Bio-consolidation theory are considered to be established by the Galyokin weighted residual method to solve the previously constructed coupling model. According to the method of model identification, the hydrogeological parameters of the study area are identified and calibrated, and the water storage rate of the Ⅰ pressurized aquifer is slightly higher than that of the Ⅱ pressurized aquifer, and the average value of the zonal water storage rate is 0.00007385, which is 0.00002048 higher than that of the Ⅱ pressurized aquifer. The coupled soil-moisture deformation analysis is carried out, and the average water content in the upper layer of the lower sand basically agrees with the change of vertical deformation, and the 0- 5h average water content decreased from 23% to 17%, after 5h in a stable state, it can be seen that pumping – recharge this process, the soil structure in the two stages of compression deformation, will reach a relatively stable state.
