Numerical Simulation Analysis of Bearing Characteristics on Super-Large Diameter Rock Socketed Pile

Abstract:

Wujiang Bridge is located on the Wujiang River in Chongqing Province in China. Based on test method of numerical simulation, the bearing characteristics of this large-diameter rock-socket pile with super-thick pile caps have been analyzed, including pile foundation load-bearing characteristics, pile-soil load sharing, and stress flow analysis of thick pile caps. The results indicated that Q-s curve of this kind of pile is approximate to linear. Under the action of ultimate load, the main load was supported by pile end résistance. And according to main stress distribution of pile cap, there is an obvious spatial truss effect phenomenon in it.
