Experimental Study of the Carrying Capacity of the Change Section Pile

The bearing capacity of the squeezed pile with the expanded branches is studied in this paper. Through the static loading test in Shandong province,the bearing capacity of three kinds of squeezed pile is compared.According to the stress of the reinforced bar,the force of different places of the pile is obtained, and the rules of the load-transfer are studied.It is deduced that the bearing capacity of the dish pile is larger than the branch piles and the general pile.In the process of the load-transfer the dish and the branches play important roles.
