Abstract :
The several kinds of pile-soil simplified analysis models were enumerated in the paper. Four analysis models were chose to build the elevated-pile-foundation FEM of a cable-stayed bridge. Then dynamic analysis and push-over analysis were done. The results of dynamic characteristics, pushover curves and form mechanism of the plastic hinges were compared by different simplified models. The truncated model was proposed in the paper because whether anti-push rigidity or plastic-hinge mechanism calculated by this model is most close to prototype. So the paper provided a simplified model for pile group foundation which could simplify calculation and guarantee the calculation precision. Research results can be used for conceptual design of bridges.
