Storage-Infiltration Effect of Rainfall for Sunken Greenbelt in Urban Road

Abstract:

In order to study the storage-infiltration effect of rainfall for sunken greenbelt in urban road, its storage-infiltration capacity of rainfall runoff was analyzed based on the rainfall balance equation of urban road in the time interval, and then the computational formulae of storage-infiltration rate was derived. Influence factors on storage-infiltration rate, such as design recurrence interval of rainfall, soil infiltration coefficient, greenbelt rate, and depth of sunken greenbelt, etc. were computed and analyzed by using the derived computational formulae with the rainfall intensity of Changchun city. Results show that: on the same condition, storage-infiltration rate of rainfall for sunken greenbelt in urban road increases linearly with the increase of soil infiltration coefficient, greenbelt rate, and depth of sunken greenbelt, and decreases with the increase of design recurrence interval of rainfall. Sunken greenbelt with depth of 0.05 ~ 0.25m can storage-infiltrate all of the rainfall that falls on the urban road when the greenbelt rate of urban road ranges from 20% to 40%. Eco-design program of sunken greenbelt in urban road is reasonable and feasible, and its storage-infiltration effect of rainfall is remarkable.
