海绵城市建设中生物滞留设施设计研究

Study on the design of the bioretention application in sponge city construction

在工程设计中,由于经验匮乏,填料选择失当,导致生物滞留设施下渗速度过快或过慢,植物无法成活,失去对雨水自然净化与处理特性。从生物滞留设施的设计、调蓄容积计算、植物选择及后期维护管理等方面介绍一种适合常州市的生物滞留设施。

In engineering design,due to lack of experience,improper filler selection,resulting in bioretention application infiltration rate too fast or too slow,plants can not survive,loss of natural purification and treatment of rainwater characteristics.This paper introduces a kind of bioretention application suitable for Changzhou city from the aspects of design,storage volume calculation,plant selection and maintenance management.
