School of Civil and Safety Engineering, Dalian... between inner column and diaphragm wall in top-down method. Top-down excavation of the Metro Line 10 in Shanghai was modeled with finite element analysis software ABAQUS and parameters of subsoil were......
Unsaturated flow and solute transport in a porous column using spherical ore particlesXiu-xiu Miao1,Ai-xiang Wu1,Bao-hua Yang2,Jin-zhi Liu3,Sheng-hua Yin1,Hong-jiang Wang11. Key Laboratory of High... for column leaching and confirmed the important simulation parameters through experiment.The unsaturated state of the variably saturated flow column and the solute transport of copper ions were studied during......
consolidation settlement of soft ground improved by floating soil-cement column on the basis of double soil-layer consolidation theory. Combining the axisymmetric consolidation model and equal strain assumption, the governing equation was derived for the consolidation of clayey subsoil reinforced by soil-cement column. By modifying the boundary condition of the interface between the improved layer......
