Research on the Formula of the Height of Bearing Push-Extend under-Reamed of the Push-Extend Multi-under-Reamed Pile

Abstract:

As there is no definite calculation formula of the height of bearing push-extend reamed of the Push-extend Multi-under-reamed Concrete Pile at present, in the paper, according to the theoretical analysis and the experimental achievements on the failure principle of the soil of the Push-extend Multi-under-reamed Concrete Pile, it is made that using the theory of shear resistance to carry on the analysis, deduce the check formula of the height of bearing push-extend reamed of the Push-extend Multi-under-reamed Concrete Pile, and it is put forward that the reliable theoretical basis of the Push-extend Multi-under-reamed Concrete Pour Pile foundation design for practical engineering.
