PROTOTYPE STUDY ON LOAD CAPACITY FOR PILE WITH EXPANSIVE BOTTOM DRILLED BY MANPOWER |
| |
| Abstract: | In this paper an estimate method for load capacity of single pile with expansive bottom which isheld by soil layer and for which the well is drilled by manpower is introduced. In test the transfer ruleof the load undertaken by the pile is analyzed. Load supported by bottom of the pile and carried bythe friction force of the soil layer around the pile are evaluated and ratio between them are estimated. |
