Research on Seepage Prevention of Ash Yardin Soft Soil
To study the seepage prevention of ash yard in soft soil,analyse the influence of settlement to the the seepage prevention,taking an ash yard in Southeast Asian country as the engineering example,a coupled analysis model of seepage field and stress field is formed by Geo-studio.By simulating the actual surcharge scheme of ash yard,the settlement of different area at different time are obtained.The results show that the maximum differential settlement in this project is 3.7m,the seepage prevention in this area should be focused on.Based on the seepage flow of 1.5mm high density polyethylene(HDPE),the 10m vertical cutoff wall cannot meet the requirement.Only when the flow channel has be cut,the vertical cut-off wall can meet the requirement,but it requires a higher cost.
