Abstract：Filter cartridge infiltration wells can effectively reduce urban surface runoff and alleviate urban flooding in sponge cities.To investigate the impact of spacing on the performance of filter cartridge infiltration wells,in-situ experiments were conducted,and a corresponding numerical model was established.The time difference for soil layers to reach full saturation was monitored using pore pressure meters,and the field data were compared and analyzed with numerical simulations.The results showed that under the same rainfall conditions,the rainwater infiltration efficiency of filter cartridge infiltration wells spaced 0.5m apart increased by 7.69%and 14.29%compared with spacings of 0.8 m and 1.0 m,respectively.Under the same cost,smaller spacing between filter cartridge infiltration wells resulted in higher rainwater infiltration efficiency.This study provides valuable insights for the application of filter cartridge infiltration wells in sponge cities.
