Influence of Rainwater Infiltration in Partial Anti-Seepage Bioretention on Adjacent Municipal Roads in Different Collapsible Grades Loess Sites

It is practical to carry out sponge cities manage rain and floods in collapsible loess areas where water resources disasters are prominent. The infiltration laws of the partial anti-seepage bioretention fields helpful ensure effectiveness safety city, which were learned from field test numerical model. seepage displacement sites with different collapsibility grades compared during rainwater model; suitability optimization suggestions for foundation treatment this structure various proposed. found that characteristics can be divided into three stages, range increases increasing time under same site type, higher level is, more significant rise range. settlement adjacent roads class II III far greater than I standard. facilities’ bottom part replaced functionality facilities surrounding actual project.
