摘　　要：城市垃圾卫生填埋场对防渗帷幕注浆的要求较高,单纯的水泥注浆,由于水泥颗粒较粗、水泥浆液凝固时的析水率较高、水泥固结体抗酸稳定性较差,很难满足设计对防渗的要求．采用粘土水泥固化浆液相关性能均能满足垃圾填埋场防渗帷幕的要求。在长沙市垃圾卫生填埋场中应用实践行之有效,为此类帷幕注浆工程提供了一种较好的注浆方法。It is higher demand of slip casting engineering of imperious curtain of municipal refuse landfill, because its coarse grain and higher sweating rate when its concretion and its antacial poor stability of cement cumulates, its difficult to meet the design specification of antiseepage by the onefold cement slip casting, the interrelated capability of solidify serosity of cement and clay can meet the impervious curtain requirement of municipal refuse landfill and which is effective for landfill and provides a good method for this type of curtain slip casting engineering.
