Abstract:The artificial piled mountains have the characteristics of large volume of earthwork, wide load distribution and long consolidation time. At the same time, due to the high requirements for foundation, it is easy to cause engineering accidents such as insufficient foundation bearing capacity or shear strength of soil. . Based on the analysis of geological conditions, calculation of foundation bearing capacity and observation of foundation settlement, the possibility of the piled mountain using natural foundation treatment scheme is studied combined with the artificial piled mountains in Nantong Zilang Park. It is concluded that natural foundation can be used to pile up a mountain more than 20 meters in the pile up project in sandy soil area, which provides some suggestions for the piled mountain in relevant areas.
