Abstract: Based on the real-time monitoring data, the main influencing factors such as land subsidence and ground water seepage around a water-rich confined foundation pit in Ji’nan are analyzed. A three-dimensional ground water stress-seepage coupling finite element model of the station end foundation pit is established by using finite element numerical analysis method, and the seepage stability of the metro station under the condition of excavation-dewatering-recharge is analyzed. Research results show that: with the excavation of the foundation pit and the continuous dewatering process, the subsidence of the surrounding stratum presents obvious groove 10-20 m away from the foundation pit. Recharge can restore the original seepage of ground water to a certain extent, slowing down the land subsidence caused by precipitation, and showing different effects with different relative locations of the recharge well from the foundation pit. The ground water rise caused by too close recharge is harmful, and too far recharge will lead to unsatisfactory effect of ground water seepage recovery. The simulation results show that recharge at a distance of about 30 m from the foundation pit can maximize the control of land subsidence and avoid excessive deformation of the foundation pit.
