| Abstract: | On the basis of analyzing the settlement surveying result on field and FEA analysis result, study has been done about the bearing capacity and settlement of cement-soil piles composite foundation under the action of flexible load. Regularity is discovered that pile-soil stress ratio varieties with time, load nature, area displacement ratio and so on, as well as settlement with time and load. Meanwhile, it is analyzed that penetrating deformation and earth-arc effect on pile top have influence on the bearing capacity of composite foundation. |
| Keywords: | flexible load: earth-arc effect cement-soil composite foundation pile-soil stress ratio |
