Abstract: The Danshan artificial landscape hill is to be located in Zhenjiang city.The hill will be constructed on the base of the abandoned quarry and will be filled with the construction waste.The maximum of thickness of the fill soil will be 50m.The thick soft clay with low strength and high compressibility in the west foundation of the hill will have great effect on the deformation and stability of the new hill.In this paper,the stability of the artificial hill slope is calculated with numerical analysis method.The results show that foundation soil and groundwater have greater impact on the artificial slope stability.As the artificial hill height increases,the excess porewater pressure and displacement in the slope body increase.The maximum change rate of the porewater pressure values is at the middle of the slope.Near the sliding surface,the excess pore pressure will reach to 150 kPa,and reduce the soil effective stress,which does not benefit to slope stability.The dissipation of pore pressure during post-construction is about 71%after construction,which is very slow.Deformation and stability of soil consolidation will require more than one year.After the deformation is stable,the maximum horizontal displacement of the foundation soil is to be 91.2cm,the vertical displacement to 70cm.The total settlement amount of the numerical results is consistent with that from the layer-wise summation method.The stability coefficient of the slope is 1.28and is calculated with FEM strength reduction method.This value is close to the result of the Limit equilibrium method.The numerical results are reliable,which can be used as the basis for engineering design and construction.
