| Abstract: | The soft foundations are consolidated by dry-cement pile in highway,then the composite ground is tested with in situ test,and the stress ratio of pile-soil is measured .Based on the data of in situ test,the varications of stress ratio of pile -soil are analysed during loading process,and the common mechanism of pile - soil load-transmission is discussed 3figs.,2tabs.,5refs. |
