| 中文摘要 |
| 以伊(伊利土)-灰(粉煤灰)复合土和普通粘土作为对比进行了卫生填埋场防渗层抗渗性能现场模拟试验,防渗层密实度1.8g/cm3,模拟降水强度1.7-2.lmm/min.试验结果表明：伊-灰复合土防渗层在抗渗性能上明显优于普通粘土防渗层;模拟降水发生后,卫生填埋场的渗滤液发生期可长达25d左右,80%的渗滤液发生于前2/5时段。 |
| 英文摘要 |
| A site test for the comparison of illite-coal fly-ash compound soil and ordinary clay using as lining material was conducted.When the density of lining material being as 1.8g/cm3 and the rate of the mimic precipitation being as 1.7—2lmm/min,it was showed that the liner of illite-coal fly-ash compound soil has much better impermeability than that of the liner of clay and after the mimic precipitation happened,the leaching liquid period could be as long as 25 days and a volume of 80% of the leaching liquid was generated in the first 2/5 period. |
