海绵设施中不同配合比介质土渗透速率研究

Study on Permeability Rate of Medium Soil with Different Proportions of Sponge Facility

依托句容市民生科技计划项目——句容市海绵城市植物适应性研究,对海绵城市建设中应用的不同配合比介质土进行了渗透试验。由于介质土是海绵设施的重要组成部分,因此筛选出一种渗透性能满足设计要求且植物生长效果良好的填料配合比具有重要的现实意义。该研究通过室外试验,在栽种植物的情况下测定其实际渗透速率,筛选具有应用价值的介质,得出了结论与建议,为句容市海绵城市建设提供了理论依据。

Based on the research on plant adaptability of Jurong sponge city,Jurong people’s livelihood science and technology project,the infiltration test of soil with different proportion medium applied in the construction of sponge city was carried out.As the medium soil is an important part of sponge facilities,it is practically significant to select a filling ratio that can not only meet the design requirements but also make the plants grow well.By outdoor experiments,this study measured the actual infiltration rate of the soil which is grew with plants,screened the medium with application value and drew conclusions and Suggestions which provided theoretical basis for the sponge city construction in Jurong City.
