摘　　要：以哈尔滨市某生活垃圾填埋场垂直防渗治理工程为例,分析了土壤固化剂和水泥在垃圾填埋层的加固及抗渗效果。通过试块取样、抽芯试样及注水试验结果对比,表明土壤固化剂和水泥均适用于加固垃圾填埋层;土壤固化剂搅拌防渗墙的早期强度值提高较快,且优于同期水泥搅拌防渗墙,两者后期强度比较接近;土壤固化剂搅拌防渗墙的抗渗性能可以满足规范要求,且优于水泥搅拌防渗墙,水泥搅拌防渗墙的抗渗性能不满足相关规范要求。Taking the vertical anti-seepage treatment project of a domestic waste landfill in Harbin as an example,the reinforcement and anti-seepage effect of soil stabilizer and cement in the landfill layer were analyzed.Through the comparisons of sample block,core-pulling sample and water injection test results,both soil stabilizer and cement are suitable to strengthen landfill layer.The early strength value of the soil stabilizer mixing cutoff wall increased faster and was superior to the cement one in same period.And the late strength values of the two walls were close.The impermeability of soil stabilizer mixing cutoff wall can meet the code and is better than that of cement whose impermeability does not meet the the relevant code.
