| Abstract: | Thirty-four compressed air drainage wells with an average depth of 15 meters were set up in an unstable landfill in Northwest China for slip control. The surface displacement, deep horizontal displacement and leachate level before and after control were compared to analyze the effect of slip control using the compressed air drainage wells. The results show that the maximum surface displacement rate is reduced from 237.3 mm/d to 78.7 mm/d after treatment with compressed air drainage wells, the maximum pumping rate of compressed air drainage wells is 255 m3/d, and the average pumping rate is 132 m3/ d, the pumping rate of the single drainage well is 3.88 m3/d. The compressed air drainage wells have low cost and short construction period, and have good effect on landfill slip control, which can provide reference for landfill slip control. |
