摘要

The foundation of the Danshan large scale piling mountain is mainly composed of the argillaceous limestone, strongly weathered diorite and soft soil in Zhenjiang of Jiangsu Province. The composition of the filling soil is consistent with the clay, which the maximum dry density and the optimal moisture content are calculated to be 1.68g/cm^3 and 18.2% respectively. The strength of filling soil is lower than the undisturbed soil after the filling soil is rolled and compacted with moderate compression. If the method of stage construction could be used, the differential setdement of the artificial mountain be greatly reduced. By the analysis of the physical and mechanical properties of the filling soil and the stability of the artificial mountain, the stability of the west and the south slope of the artificial mountain are worse than the east and the north. The stability results by numerical simulation and the limit equilibrium method are very good consistency.
