| Abstract: |
| Using the method of horizontal column infiltration, unsaturated liquid infiltration characteristic of two kinds of NAPL (kerosene and PCE) in different texture soil were studied. The results showed that: there exist same infiltration characteristic of NAPL with water in soil, the curves of accumulative infiltration capacity of NAPL in different soil could be describe with equation of Koctiakov (F=atα); NAPL infiltration rate decrease with increase of soil clay content, showed sand soil>Huang mian soil>Lou soil; There was a large infiltration rate of PCE in soil comparing with kerosene, there may be the effect of dynamics viscosity; there have restrain function of soil compress on NAPL infiltration, NAPL infiltration rate decrease with increase of soil bulk density. |
