摘　　要： 以建筑废弃料中的加气混凝土和固结砂浆为土壤填料,采用常水头渗透实验,研究其对城市绿地土壤渗透性的改良作用,得出结论:这两种土壤填料的渗透性远大于纯土壤的渗透性,为建筑废弃料用于城市低影响开发提供了新的思路;加气混凝土和固结砂浆均呈碱性,针对大城市及部分工业城市的酸雨现象,雨水经地表流入地下时,对雨水pH进行中和改善,有效保护地下水。 In the construction waste materials,the aerated concrete and the consolidated mortar are used as soil fillersthrough constant head permeability test. Through the study of the improvement of soil permeability of urban green space,we draw a conclusion that these two kinds of soil filler permeability is much better than that of pure soil permeability,which provides a new way to solve the problem of low impact development of construction wastes for city. The aeratedconcrete and the consolidated mortar are alkaline,which make them useful specific to the phenomenon of acid rain in thebig cities and some industrial cities. When the rain flow into underground through the earth's surface,the two kinds of soilfillers can improve the pH value of rainwater,and effectively protect the underground water.
