基于土体储水能力的降雨入渗调节系统

The rainfall infiltration regulation system based on soil water storage capacity

对城市中占地面积最大海绵体——土体的储水能力进行了分析,结合非饱和土力学与水气两相流理论,提出一种通过调节土体孔隙气压力以达到缓解城市内涝、促进地下水补给的入渗调节系统,该系统通过自然途径与人工措施相结合的方式,在缓解城市内涝、促进水资源的综合利用方面有着重要作用。

This paper analyzed the water storage capacity of cavernous-soil with largest occupied area of the city,combining with the unsaturated soil mechanics and air water two phase flow theory,proposed a infiltration regulation system through the pore air pressure to alleviate the city water logging,promote the groundwater replenishment. The system through the way combination of natural method and artificial measures,had important role in alleviating urban water logging and promoting the comprehensive utilization of water resources.
