| Abstract: | The behaviors of granite residual clay and its effects on the bearing capacity of hand-dug piles were expounded in this paper. Then 4 loading tests were performed to analyze the distribution of the shaft resistances and the end bearing of the piles embedded on granite residual clay. Based on the results of 4 loading tests, a method to calculate the bearing capacity of the pile was presented. Finally, 92 loading tests were employed to analyze the influences of groundwater on the bearing capacity of the piles. |
| Keywords: | granite residual clay hand-dug pile groundwater bearing capacity shaft resistance loading test |
