| Abstract: | Through finite element analysis method, mechanical characteristic of the flexible foundation and stone pile composite ground has been done by means of numerical simulation method. For stone pile composite ground, some basic mechanical characteristic regularity has been obtained, such as the additional stress distribution characteristic of soil and pile, the relationship between load level and stress of the top pile and pile body load bearing rate, the relationship between the pile-soil module ratio and stress of the top pile and pile body load bearing rate,the relationship between the pile-soil stress ratio and load and area replacement ratio etc. All these provide reference for construction design. |
