| 摘 要： | 卫生填埋场底部需设置低渗透率的粘土层,日本粘土资源匮乏.本研究利用膨润土作为卫生填埋场本地砂土的添加剂,提高和改善防渗能力.卫生填埋场本地压实砂土的渗透率为4.65×10^-5cm/s,膨润土作为添加剂与本地砂土混合成复合土,当添加率为10%时,渗透系数提高到3.72×10^-8cm/s,满足日本卫生填埋场建设标准.

| Abstract: | Low permeation of compaction soil liner is used in sanitary landfill.Because of scarcity of soil resource in Japan,by using of Bentonite as addition,it can decrease hydraulic conductivity of sand liner.The hydraulic conductivity of local compacted sand is 4.65×10-5 cm/s,but bentonite-sand mixture decrease to 3.72×10-8 cm/s,which measure up the standard of landfill line system in Japan. |
