This study explores its application to dewater landfilled waste to facilitate...

... of the representative unit and r(ϕ) exclusively affect the dewatering rate of the clayey slurry, while the gel point and P_y(ϕ) influence both the dewatering rate and the final deformation. More specifically, the determination of P_y(ϕ) and r(ϕ...

...G. Zheng; Q. H. Li; X. S. Cheng; D. Ha; J. C. Shi; X. R. Shi; Y. W. Lei In deep excavations, pre-excavation dewatering (PED) usually causes notable diaphragm wall (D-wall) deformation and ground settlement. However, this problem has not attracted sufficient attention. In this paper, the mechanisms...
