Abstract

The laboratory hydraulic conducti vita tests with rigid wall permeameter were performed to study the effects of waste leachate on the permeability of a marine clay. The marine clay and waste leachate for this study were sampled from Kimpo Wastefills, and the hydraulic gradients applied to the clay specimens aTe relatively high from 37.5 to 225. The test results show that the permeability of a marine clay is increased with increasing the concentration of leachate and with decreasing the hydraulic gradient. And also both the liquid limit and the plasticity index of the marine clay miRed with waste leachate decrease with increasing the concentration of leachate.

폐기물의 침출수가 해성점토의 투수성에 미치는 영향에 대해서 연구하기 위하여 실내에서 강성벽의 정수위투수시험을 시행하였다. 본 연구에서 이용한 해성점토와 침출수는 김포 폐기물 매립장에서 채취하였으며 공시체에 가한 동수경사는 비교적 큰 값인 37.5~225 정도이었다. 연구결과 침출수의 농도가 클수록 그리고 동수경사가 작을수록 침출수에 대한 해성점토의 투수계수는 증가한다. 또한 침출수와 혼합시킨 해성점토의 액성한계와 소성지수는 침출누의 농도가 증가할수록 감소한다.
