| Abstract: |
| Finger flow can be produced in the layered soil which the structure is the “soil top and sand bottom”. In the condition of finger flow happened, The migration of chloride ions with different concentrations in layered soil was studied. The results showed that the chloride concentration in the upper soil increased first and then decreased in the vertical direction. The chloride concentration in the transition area in the lower drainage area did not change much. The chloride concentration in the accumulation area near the bottom of the test increased. The chloride concentration in the fingertip was higher than that in the transition area. The chloride concentration in the fingertip was higher than that in the transition area The transfer efficiency is very high, accounting for 35-55% of the mass of chloride ions in the soil. |
