摘　　要：针对威海市垃圾处理厂截污坝帷幕渗透系数 K≤ 5 .5 2× 10 - 7cm/ s的较高防渗要求 ,在截污坝帷幕灌浆工程中采用水泥灌浆结合 HS酸性水玻璃材料对基础进行复合灌浆处理 ,采用这种工艺后的灌浆效果完全满足透水率<0 .0 44 LAiming at the high seepage proof requirement that the permeability cofficient K should be equal to or less than 5.52×10 -7 cm/s for the curtain of interception pollutant dam belonging to Weihai Refuses Treating Plant,the composed grouting foundation treatment was performed using cement grouting admixing a HS acidic water glass material.The grouting effect has met the design requirement that the permeability rate is less than 0.044 Lu.
