【 摘 要 】

Pervious pavement of large parking lot in sponge city is a new structural form, which is conducive to solving the problem of deterioration of urban ecological environment. The hydrological characteristics of large permeable parking lot are studied. The results show that the effect of large permeable parking lot on flow delay is obvious. No runoff occurs in the structure of large permeable parking lot when the maximum rainfall intensity reaches 0.968 mm/min. When the recurrence period increases from one year to 100 years, the percentage of total runoff reduction are 100%, 66%, 56%, 48%, 44%, and the peak flow reduction rate are 100%, 58%, 50%, 46%, 41%, respectively. With the extension of rainfall recurrence period, the total amount of runoff reduction in large permeable parking lots increased, and the reduction rate showed a downward trend. The research results can provide reference for the construction of large permeable parking lot in sponge city.
